Morphology

tack + on

The meaning 'to add or attach something extra' is directly derivable from 'tack' (to fasten) combined with the directional/locative particle 'on' (onto), so the action of fastening or putting something onto something else clearly maps to adding or attaching. This verb+particle pattern is common and predictable in English, so an average B1 learner who knows the constituents would most likely infer the intended meaning.

Etymology

The phrase tack on comes from the image of fixing something with a tack, a small nail. If you literally tack on a scrap of paper to a page, you are adding it as an extra, so today tack on means 'to add something extra'.
