This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means guess so the verb vocab version is to guess. Alternatively, you can learn this as to sense or to presume.
The reading for this is actually the same as what you learned with the kanji, but the さつ is shortened to さっ. If you had to guess be sure to guess with the shorter つ.
