-ing

Save This Word!

a suffix of nouns formed from verbs, expressing the action of the verb or its result, product, material, etc. (the art of building; a new building; cotton wadding). It is also used to form nouns from words other than verbs (offing; shirting). Verbal nouns ending in -ing are often used attributively (the printing trade) and in forming compounds (drinking song). In some compounds (sewing machine), the first element might reasonably be regarded as the participial adjective, -ing2, the compound thus meaning “a machine that sews,” but it is commonly taken as a verbal noun, the compound being explained as “a machine for sewing.”

how to pronounce -ing

The common suffix -ing2 can be pronounced in modern English as either [‐ing] /‐ɪŋ/ or [‐in], /‐ɪn/, with either the velar nasal consonant [ng], /ŋ/, symbolized in IPA as [ŋ], or the alveolar nasal consonant [n], /n/, symbolized in IPA as [n]. The [‐in] /‐ɪn/ pronunciation therefore reflects the use of one nasal as against another and not, as is popularly supposed, “dropping the g, ” since no actual g -sound is involved.
Many speakers use both pronunciations, depending on the speed of utterance and the relative formality of the occasion, with [‐ing] /‐ɪŋ/ considered the more formal variant. For some educated speakers, especially in the southern United States and Britain, [‐in] /‐ɪn/ is in fact the more common pronunciation, while for other educated speakers, [‐ing] /‐ɪŋ/ is common in virtually all circumstances. In response to correction from perceived authorities, many American speakers who would ordinarily use [‐in] /‐ɪn/ at least some of the time make a conscious effort to say [‐ing], /‐ɪŋ/, even in informal circumstances.
