I learnt this word today. It’s basically when a child can’t yet form full phrases so uses singular words combined with inflections and gestures to get the point of an entire phrase across. When a kid says “up” looking up at you all excited, clearly they want to be picked up, that kind of thing.
This got me thinking about slang and how so many people this day shorten whole words or phrases into singular words, often with three syllables or less so it’s extremely quick to pronounce. Why not learn a new word that actually has the meaning of an entire phrase, rather than making your own? Schadenfreude means getting joy from the misfortune of others. Apanthropinization is the withdrawal from the world and any problems and resignation of any current concerns. Scripturient is the act of feeling a strong and violent urge to write something. Words like this need to be learnt and used, or the language dies.
