倹 is built from the 亻 (person (left)) and 僉 (all / together (in 検·険)) components.
It belongs to a phonetic family with 検, 験, 険, and 剣 — they share the 僉 component and the reading ケン.
A common word using 倹 is 倹約 (けんやく), meaning “thrift, economy, frugality”.
Don't confuse it with 験, 険, and 検 — 馬 test, 阝 steep, 木 examine, 亻 frugal
