consign, requesting, entrusting with, pretend, hint
託 centers on handing something over to another person's care or authority: consigning goods, entrusting a task, or making a request. The "pretend" and "hint" senses are extensions where one entrusts a hidden meaning or feigned intention to someone else's interpretation.
託 combines 言 (words) with 乇, which likely contributes the sound and may have originally depicted a sprout or plant, though the exact semantic role is uncertain. The character expresses entrusting or consigning through speech.
Words (言) are entrusted to someone, like handing over a message. The right side 乇 looks like a person reaching out to receive something, so together they show entrusting words to another.
For タク, imagine entrusting a package to a tack shop: tack -> タク, and you leave your words with the shopkeeper.
