CKに関しては以下のようなルールがある
【1】ckで始まる語はない。
【2】単音節の語が最後 c で終わることはない。これは、ckと書かれる。(母音に続く語もcで終わらないと古元典にはあるが、icの接尾辞との関係は不明)
ckで終わる語の例
attack back black block brick buck check chick click clock cock crack deck dock duck fleck flick flock frock hack jack kick knack knock lack lick lock luck mock neck nick pack pick pluck quack quick rack rock ruck sack shack shock slack slick snack speck stack stick stock tack tackle thick tick track trick truck tuck wick wreck
例外
cで終わる単音節の語
arc chic
ckとなるべきなのに省かれている語
public music maniac
(おまけ)その他のcで終わる語
接尾辞【-ic】 形容詞化(～的な)
接尾辞【-ic】 名詞化
があるためか(その他にもたくさんの接尾辞があります)
子音+cで終わる語
franc orc talc
i以外の母音で終わる語(ac・ec・oc・uc)
bivouac havoc
icで終わる(接尾辞 -icとそれ以外とを分類中)
