And here is a saying you’ll hear often. It is generally used with reference to Gaelic. As Gaelic is feminine, we use the pronoun i (she).
Cleachd i no caill i!
Use it or lose it!
This phrase has two regular verbs: cleachd (use) and caill (lose).
cleachd
use
a’ cleachdadh
using
caill
lose
a’ call
losing
As with most regular verbs, where possible, we lenite them to form the past tense.
Chleachd mi an càr an dè,
I used the car yesterday,
agus chaill mi na h iuchraichean agam.
and I lost my keys.
