terminology - Is there a lingustic term for okurigana omission?

Is there a (Japanese) linguistic term for okurigana omission (cases when 問い合わせ is written as 問合せ, etc.)? If not then what would be a concise way to refer to the phenomena (in Japanese)?

Answer

Being a non-linguist, I have no idea if this term is used in linguistics, but our 文化庁{ぶんかちょう} (Agency for Cultural Affairs) calls it 「許容{きょよう}」 ("tolerance").

To refer to the phenomenon, you could use a phrase like:

「誤読{ごどく}の可能性{かのうせい}が低{ひく}い（単{たん}）語{ご}の送{おく}り仮名{がな}の省略{しょうりゃく}」

That would be understood by all native-speakers, I promise.
