Surface Forms

a thing or two singular
things or two plural

Morphology

a + thing + or + two

Literally the phrase composes as 'one or two things', so a B1 learner who knows 'thing' and 'two' can infer a meaning like 'some things' about a topic. However, its conventionalized use to imply practical knowledge, skill, or a degree of expertise (often with a boastful or evaluative nuance) is a pragmatic/idiomatic extension not fully predictable from the parts, so it is only partially transparent.

Etymology

A thing or two comes from the image of someone showing a small number of useful items: they hold up a thing and then two tools from a box to show what they can do. So, if you know a thing or two about something, you have 'some useful knowledge' you could show or teach.
