:''For weak and strong forms of a
differential equation, see
finite element method.''
In the
phonology of
stress-timed languages, the 'weak form' of a word is a form that may be used when the word has no stress, and which is
phonemically distinct from the 'strong form' used when the word is stressed. The strong form serves as the
citation form. A weak form is an unstressed
syllable, and is therefore distinct from a
clitic form, which is not a syllable at all but rather fused with the end syllable of an adjacent word. A word may have multiple weak forms, or none. In some contexts, the strong form may be used even where the word is unstressed.
English
In
English, most words will have at least one stressed syllable, and hence no separate strong and weak forms. All words which do have distinct strong and weak forms are monosyllables, and are usually
function words or
discourse particles. For most of these, the weak form is the one usually encountered in speech. As the extreme example, the strong form of the
indefinite article ''a'' is used only in the rare cases when the word is stressed: naming the word, or when emphasizing indefiniteness. For instance:
:Question: "Did you find the cat?"
:Answer: "I found ''a'' cat." (i.e. maybe not the one you were referring to).
Otherwise, the weak form is used for ''a''.
The main words with weak forms in
Received Pronunciation are:
:''a'', ''am'', ''an'', ''and'', ''are'', ''as'', ''at'', ''be'', ''been'', ''but'', ''can'', ''could'', ''do'', ''does'', ''for'', ''from'', ''had'', ''has'', ''have'', ''he'', ''her'', ''him'', ''his'', ''just'', ''me'', ''must'', ''of'', ''shall'', ''she'', ''should'', ''some'', ''than'', ''that'', ''the'', ''them'', ''there'', ''to'', ''us'', ''was'', ''we'', ''were'', ''who'', ''would'', ''you''
Other dialects or accents may have others. Many
Americans have a weak form for ''your'', which is occasionally spelled "yer". In
Hiberno-English, there is a weak form for ''my'', often spelled "me". A greater difference between strong and weak forms, and a more widespread use of weak forms, are associated with less formal
registers, and may be indicated in writing by
eye dialect spellings, such as ''’em'' for ''them'' . The most formal register in this sense is
singing, where strong forms may be used almost exclusively, apart from ''a''.
In deriving weak forms from strong forms, the
vowel is usually more
central and may be
shortened, sometimes merging to a
syllabic consonant with any following , or . Changes to consonants are less frequent: an initial
h is dropped unless the word is at the start of an
utterance, and
dental consonants may be
elided at the end of the word. For example:
★ The word ''and'' has strong form and weak forms , , , .
★ The word ''to'' has strong form , weak form before vowels, and weak form before consonants.
The 'em'' form of ''them'' is derived from the otherwise obsolete synonym ''hem'': an unusual form of
suppletion.
Some weak forms have restricted usage. For example, in RP usage:
★ Dropping the of ''her'' is common in "I saw her yesterday" but not in "I saw her mother" (possessive ''her'').
★ Demonstrative ''that'' uses the strong form even when unstressed. "I like that colour" (demonstrative, strong), as against "I like that you like it" (conjunction, weak).
★
Stranded auxiliaries and prepositions use the strong form. "I found what I'm looking for." (stranded ''for'', strong) as against "I'm looking for money" (''for'' before
noun, weak).
