Word Nuance & Usage

'Ingress' is a formal or technical term (commonly paired with its opposite, 'egress', in property law, architecture, and engineering) rather than an everyday word for an entrance.

Word Origin & Etymology

Borrowed in the late Middle Ages from Latin 'ingressus' ('a going in'), the past participle of 'ingredi' ('to enter'), formed from 'in-' ('into') and 'gradi' ('to step, walk').
