Surface Forms

Morphology

last + thing + on + one + mind

The meaning 'not a priority or concern' is directly inferable by combining 'last' (final/least important) with 'thing' and the locative metaphor 'on one's mind' (what one is thinking about or concerned with). This compositional reading is cross-linguistically common and follows straightforward semantic logic, so a B1 learner who knows the constituent words would very likely understand the expression.

Etymology

Last thing on one's mind gives a simple picture: imagine your thoughts in a list and the last thing sits at the back of your mind, so you are not thinking about it now. That's why it means 'not a priority' or 'not something you are likely to think about'.
