What does entrench mean?
Entrench is a verb that describes establishing something so firmly that removing it becomes extremely difficult. Its most common modern use is figurative: attitudes, customs, institutions, or power structures become entrenched when they take deep root and resist reform — as in entrenched interests or an entrenched belief system. The word carries a connotation of stubborn permanence, often with a critical edge when applied to practices seen as outdated or unjust. The term originated in a literal military sense, referring to digging troops into trenches for protection, a meaning that dates back centuries and still survives in military contexts. Derived forms include entrenched (adjective/participle) and entrenchment (noun). Because it vividly captures the difficulty of dislodging what has settled in, entrench is especially valuable in writing about politics, organizations, and social change, where it signals not merely existence but resistance to alteration.
To establish something so firmly that it is very difficult to change or remove.

Frequently used in passive constructions.
To dig or position troops in trenches for defensive purposes.
"The regiment entrenched itself on the hillside."
Original literal sense; now primarily historical or military-technical.
Entrench literally means digging a trench — and figuratively, it's how ideas dig their own defensive ditches in our minds.

Etymology of entrench
Entrench derives from the prefix en- (from French/Latin meaning 'in' or 'to cause to be') combined with trench, which traces back through Old French trenche ('a cut, slice') to the verb trenchier, ultimately from Latin truncare, 'to cut off or lop short.' The literal military sense of digging into trenches appeared first in English around the late 16th century, with the figurative sense of firmly establishing something developing later. Cognates sharing this root include trench itself, intrench (a variant spelling), retrench, and trenchant.
