From Hull AWE
- This pattern of shifting stress in words that look identical but belong to two separate word classes is quite common in English. Quirk (Appendix I.56 B) remarks: "When verbs of two syllables are converted into nouns, the stress is sometimes shifted from the second to the first syllable. The first syllable, typically a Latin prefix, often has a reduced vowel /ə/ in the verb but a full vowel in the noun:
- There follows a list of some 57 "words having end-stress as verbs but initial stress as nouns in Br[itish] E[nglish] (in Am[erican] E[nglish], many have initial stress as verbs also)". This list is the foundation of AWE's category:shift of stress.
