To Abbreviate
To Omit
transitive verb, godan verb
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means abbreviation, so the verb vocab version is to abbreviate or to omit.
The reading is, strangely, the same as the reading you learned with the kanji. りゃくす.
