'trench-like' originates from the word 'trench,' which comes from Old French 'trenchier,' meaning 'to cut.' The suffix '-like' is used to form adjectives indicating resemblance.

The word 'trench' evolved from the Old French 'trenchier' to Middle English 'trenche,' eventually becoming the modern English 'trench.'

Initially, 'trench' referred to a cut or furrow, and over time, it evolved to mean a long, narrow ditch. The suffix '-like' adds the meaning of resemblance.
