persuade, recommend, advise, encourage, offer
勧 centers on urging someone toward a positive action: persuading, recommending, advising, encouraging, or offering an option.
勧 combines 力 (strength, effort) with a phonetic element derived from 雚 (a type of bird), which contributed the sound and the idea of urging or encouraging.
The right side is 力 (power, effort). The left side looks like a bird (隹) over a small base. Imagine using effort to urge a bird to fly: you persuade and encourage it to take off.
For カン, imagine a can of energy drink being offered to persuade someone: can -> カン, and the effort (力) encourages them to act.
