Rules
The rule is to add the morpheme -ing in all cases.
Orthographically:
1. If a word ends in -e, delete it and add โingโ, unless it ends in -ee, -ie, -oe, or -ye. If it ends in -ie, replace โieโ with โyโ and add โingโ, otherwise just add โingโ. For words ending in -ue, just adding โingโ is generally a less common alternative.
If a word ends in -ce or -ge, deleting the โeโ may lead to (apparent) confusion with a similar word ending in -c or -g. The โeโ will be retained if there is a (relatively common) verb that is the same apart from the e (so hinge โ hinging but singe โ singeing); deletion of the e is the prescriptive norm but retention seems to have become more common in certain cases, like โwhingeingโ Google ngram for โwhingeingโ, โwhingingโ). For words ending in -dge, just adding โingโ is a less common or non-standard alternative.
- ice โ icing
- true โ truing
- free โ freeing
- lie โ lying
- toe โ toeing
- dye โ dyeing
- eye โ eyeing
- sautรฉ โ sautรฉing
- fรชte โ fรชting
- queue โ queueing (perhaps the more common form today)
- hinge โ hinging
- singe โ singeing
- sing โ singing
- whinge โ whinging or whingeing (the more common form today)
- badge โ badging (โbadgeingโ is non-standard but de-badgeing has been observed in connection with automobiles)
2. If a word ends in -c, add โkingโ (panic โ panicking). May not apply to to abbreviated words (mic โ micing, spec โ speccing; there are alternatives here).
3. In most varieties of English (but not in US-English), if a word ends in -l after a single vowel, add โlingโ (cancel โ cancelling), but โparallelโ is an exception (parallel โ paralleling). US-English doubles the l only if the final syllable is stressed (โexcellingโ but โcancelingโ).
4. If a word ends in -b, -d, -f, -g, -k, -m, -n, -p, -r, -s, -t, -v or -z preceded by a single vowel, double the final consonant and add โingโ. Does not apply to an unstressed final syllable (fillet โ filleting but sublet โ subletting). Sometimes a final -s is doubled even when the syllable is unstressed (focus โ focusing or focussing).
5. Otherwise, just add โingโ (the morphological rule). GrounderUK (talk) 23:04, 10 February 2024 (UTC) [originally at implementation Talk:Z13091].
