Your comment made me realise that this was a key part of my development as a roleplayer - I played a Kenku for a small campaign and I had decided to lean into the mimicry aspect of Kenkus and build myself a phrasebook over the course of the campaign.
This meant that there were many times that I wanted to say something, but the words I had at my disposal either weren’t quite right or not there at all. If I wanted to express my character properly, I needed to describe body language and actions more.
