Where there is no vowel before the Shun Hook, the
lightly sounded P is omitted and stroke Em is used:

R Hook is described together with Doubling

same sound = imper/imber
Never takes L Hook, use either stroke Ell or
compound consonant Pel Bel.

Halving
Basic Imp/Imb cannot be halved, as that form is
already allocated to MD. Only the hooked form can be halved.
1. When no vowel follows, the P is hardly
sounded. It is therefore omitted and a halved Em is used to
represent the M(P)T sound. This
reflects the pronunciation and produces a shorter outline. Do
not be misled by the final "-ed" in the longhand spelling, the
pronunciation is always the T sound. The compound sound MBD (i.e.
with no vowels between) does not occur, which is why the halved and
thickened Em stroke was allocated to the sound of MD.

pumped plumped prompt pre-empt bumped tempt tramped dumped

champed chomped jumped camped encamped unkempt decamped

cramped crimped clamped skimped scrimped exempt

lumped slumped limped gazumped revamped thumped romped shrimped

humped stamped stomped swamped sumptuary

empty temptation temptress impromptu presumptuous
have a vowel after the T sound, so would require a stroke anyway, to write the
vowel against. With such words you could use stroke Imp if you wanted, but your
outline would not match the theory book or the dictionary. You cannot however
use a thickened halved Em, because that is not available, being already used to
represent plain MD.
Compare the following pairs: MT which represents M(P)T, and
MD:

bumped bummed tempt tamed dumped deemed

ramped rammed cramped crammed stumped stemmed
Note the halved Em behaves as per normal halving rules, it can
have a vowel between the M and the T sounds:

prompt
promote prompter promoter limped
(="limt")
limit
Names and place names must remain clear, as context
cannot help, so stroke Imp is used, even though the P sound may be
spoken just as lightly as the above words:

Ampthill Hampden Hampton Hampstead
compare Hamstead

Compton Crompton Bampton
Frampton Southampton*
*correct
with one longhand H, no aspirate is pronounced or required in the outline
Speakers will vary according to how much they
pronounce the light P sound, and some may leave it out altogether,
but the shorthand outlines should remain constant. What people say
when they are speaking carefully may be entirely different from
their pronunciation in actual fast usage.

2. If there is vowel after the MP/MB, add
stroke Tee or Dee:

impute trumpet strumpet strombite crumpet ambit gambit

wombat limpet limpid embayed imbued impede

stampede sambaed mamboed ombudsman rhomboid flambéed shampooed
Top of page
3. Halved if Hooked
Can be halved if it has an R Hook or N Hook:

hampered rampart whimpered Lambert slumbered cambered clambered scampered

impend/impenned*
impugned impound impawned ambient
Note:
impended impounded
*impenned = past tense of impen, to enclose in a
pen

dampened championed campaigned lampooned lambent rampant flamboyant
4. Not halved when it has Shun Hook, use halved Ish+N Hook:

ambitioned*
impassioned
impassionate
*adjective = full of ambition, suggested outline, not in shorthand dictionary. See also Theory 9
Shun Hook/halved stroke page.
Top of page
Doubled or with R Hook

The sound of imper/imber (with the accent on the first syllable and
a slurred second vowel) is represented both by doubling and by using
the R Hook. The two strokes shown above represent identical sounds,
and which to use depends on the convenience of the join.
See also the Quick Reference Table on
Theory 11
Doubling page
Use the doubled stroke when it is the only stroke in
the outline, or after a downstroke or Em:

amber ember umber sombre/somber simper stamper

pamper pumper plumper bumper Bamber

tamper tamperer temper temperament temporal*
*This is exceptional, as the vowel after the P is "or" not "er", but doubling is
used to prevent similarity with temporary/temporarily, see
above

temperature distemper damper dumper

chomper chamber jumper September December
but November
(contraction)

mumper thumper
Northumberland
Top of page
Use the hooked form in all other cases i.e. after
upstrokes and straight horizontals (the doubled stroke would join perfectly
well to a horizontal, but the hooked form is preferable so that it
can be halved for past tenses):

camper/camber scamper Camberwell Camberley Cumberland

cucumber Stogumber whimper romper reimburse

hamper humper/Humber lumper/lumber/lumbar slumber limper/limber Lamberhurst
If the Imp has an N hook, the doubling adds -der
(these 4 words are the only examples):

imponderable
imponderability imponderous impounder
Note:
ponderable ponderous
Past tenses: the doubled form changes to Em and
halved Per/Ber:

tampered tempered timbered simpertinentimpered chambered pampered
As doubling of stroke Imp only adds -er, to add
the sound of -eter, stroke Tee with R Hook is used:

trumpeter embitter imputer Lampeter
If there is no central vowel, then the P sound is
only lightly sounded and need not be represented: use Em doubled, which adds the
-ter sound as per normal doubling rules:

prompt prompted prompter tempt tempted tempter

Plumptre
(plump-ter & plum-ter)
The dictionary gives no final vowel for the first
outline. Isaac Pitman's Phonographic & Pronouncing Dictionary of 1894 gives the
name "Plumptree" same as the first outline but with a heavy final vowel to
match the spelling. This is a town-derived surname = place of plum trees.

Note: pumpernickel* sempervirent*
shrimper**
shrimp
*For ease of joining
**Not doubled, to provide added distinction from "shrimp" as both
are nouns
Top of page
When not to use
1. Vowel between: not used if there is vowel between the M
and the P/B sounds:

map mapped mope moped
(past tense of mope)
moped
(bike)
maypole myopia

mob mobbed mobber mobile Namibia

amoeba/ameba demob somebody homebody
2. Con/com dot: the representing of
con/com/cum, either by the initial dot or by disjoining, includes the M sound,
so only the following P or B stroke needs to be written:

compel compare complain comprise
recompense encumber
Top of page
3. MBL: If no vowel between, or only a slurred
unaccented vowel, use plain Em and Pel/Bel:

ample amply amplify employ imply
implication

implore implode amble umbles Embleton
emblem

emblazon pimple preamble bumble bramble

temple Templeton template tumble tremble dimple

Campbell
(pronounced "camble")
gamble/gambol crumple crumble scramble

jumble fumble thimble assembly
shambles shambolic*
*not in dictionary, suggested outline
based on "symbolic" below

sombrous sombrero sample example
simple

stumble symbol/cymbal symbolic
but symbology

mumble nimble ensemble*
resemble rumble
*Anglicised pronunciation

humble Hambleton wimple Wembley
Wimbledon
Top of page
4. MPR MBR with no vowel between, use plain Em and Per/Ber:

empress impress impression imprint imprison

improper improvise imprudent lamprey

embryo embrace Ambrose ambrosia embrasure

embroil umbrella imbroglio umbrage

Flamborough Northumbria Cumbria Hambrook

Note also
Hamburg Cambourne Wimborne

5. Derivatives
starting Im+per and Im+pl
1. If the word is derived from one that uses a hook
i.e. PR PL BR BL, retain that form and use stroke Em before it:

person impersonate personal impersonal perfect imperfect*
*Contraction

permanence impermanence perforated imperforated

permeable impermeable permissible impermissible

placate implacable placement
emplacement plausible implausible
Top of page
6. Compound words: not used where the M and
P/B belong to different words:

timepiece tomboy dumb-bell homebred homebrewed

bumboat gumboot gumboil hymn-book

time-bomb plum-pudding stormbound lamp-post*
*choice of full outline or contraction (this contraction is ignoring
the rule, as the outline is sufficiently distinctive)
7. PH: Not used where the longhand P is part
of PH = F sound:

triumph lymph nymph galumph

amphitheatre amphibian amphora samphire

pamphlet emphasise symphony emphysema
Top of page
8. Silent B: A longhand silent B has no place
in shorthand and the M is treated as normal:

aplomb* plumber bomb bombing tomb dumb
*Anglicised pronunciation (from
French)

comb succumb climb crumb

lamb limb thumb womb numb number
(= more numb, pronounced "nummer")

lambed limbed thumbed combed climbed
