And specifically for expressing you hurt yourself, we teach children to express that they're hurt far earlier than they learn actual speech. So from ~1 we teach them to say "Ow" (or some variation), but then the words change from that to "hurt", and into a full sentence "I hurt myself", which is also redundant (myself and I imply the same thing, so why do we use both in that sentence in English?).
Anyhow just a thought as I'm feeding my son breakfast. "Would you like some breakfast" in English turns into 2 words in his second language.
