Common Mistakes
- Pronunciation: Not /trɛnʃ/ or /trɛntʃ/. It's /trenʧ/. Spelling: Confusion with 'trench' vs. 'trentch'. Using 'trench' for a natural valley or ravine (it is man-made).

FAQ
Frequently Asked Questions
No. While its most famous use is military (trench warfare), it is common in geology (ocean trenches), archaeology, civil engineering (utility trenches), and agriculture (drainage trenches). 'Trench coat' is also common.
A ditch is usually shallower, wider, and often for drainage by the side of a road or field. A trench is typically deeper than it is wide, man-made for a specific purpose like protection, excavation, or laying pipes, implying more deliberate construction.
It's the past participle/adjective from the verb 'entrench' (to dig a trench around, to fortify). Metaphorically, it means firmly established and difficult to change (e.g., 'entrenched habits', 'entrenched inequality').
It rhymes with 'bench' and 'wrench'. The IPA is /trenʧ/ for both British and American English.
