Verb

rougir

1. (intransitive) to redden, blush
   • 1845, Alexandre Dumas, Le Comte de Monte-Cristo, page 52:

     — Le mari, le mari, dit Caderousse en riant, pas encore, mon capitaine ; essaye un peu de faire le mari, et tu verras comme tu seras reçu !
     Mercédès rougit.

     "Husband, husband," said Caderousse laughing, "not yet, my captain; just try to act as a husband, and you will see how you will be received!"
     Mercedes blushed.

Conjugation

This is a regular verb of the second conjugation, like finir, choisir, and most other verbs with infinitives ending in -ir. One salient feature of this conjugation is the repeated appearance of the infix -iss-.
