How to fix

Delete the letter and retype the word (おもしrおい → おもしろい).

Why it matters

A single Latin letter inside a Japanese word (おもしrおい for おもしろい) is a key pressed in romaji input that never became kana. The reader stops at the word, and search does not find it. It is a typing slip, not a style.

What it does not flag

Capitals (A社, Bさん), runs of two or more letters (while文, note) and code are not reported. A letter followed by a particle (変数xが, まずxを, をxで) is read as the name of a variable, and a letter followed by a kanji (のx座標) is not reported either. A letter after katakana (サイズm, プランb) is read as a label, and paths (/docs/…) are not read. A lone vowel (eラーニング, iモード) is part of the word, since romaji input turns a vowel into kana at once and never leaves it behind.

Turning it off or relaxing it
