declension, not conjugation
This is a nit error report for Greek from English relating to the "Plurals" lesson. Couldn't find another place to put it except a bug report, and that didn't seem to fit exactly.
The "Asterisks" section at the end of the lesson tips speaks of how foreign words are not "conjugated". The lesson is on forming plurals for nouns and adjectives, so it should say "declined". Verbs have conjugations; nouns and adjectives have declensions.
In the skill "Personal objective pronouns" Tips and Notes says
Personal pronouns are also conjugated.
