Morphology

slip + one + mind

The verb 'slip' combined with 'mind' evokes a simple motion metaphor — something sliding out of one's memory — so a learner who knows 'slip' and 'mind' can plausibly infer the meaning 'forget'. However, this relies on a metaphorical mapping rather than a strictly literal composition, so the relation is only partially predictable without prior exposure.

Etymology

The idiom slip one's mind gives a simple picture: imagine a small note or thought quietly slip off the edge of your mind like a coin sliding from a table. Because the idea has 'slipped' away and you can't reach it, the phrase means 'to forget'.
