Surely there must be an etymological connection between ‘mwt’ and ‘mother’ (Greek μητηρ, German ‘mutter’)?

Given that the ancient Egyptians routinely wrote the determinative for ‘nrt’ when referring to their mothers, does that say anything about the way they saw things? Is there anything polysemic about it?

Voracious reader… swallowing a dictionary (let’s hope it’s not Erman & Grapow)…
