'US-like' is a modern English compound formed from 'US' (an abbreviation for 'United States') and the suffix '-like', which means 'resembling or characteristic of'.

The suffix '-like' has been used in English since Old English to form adjectives meaning 'similar to' or 'having the characteristics of'. The use of 'US' as an abbreviation for 'United States' became common in the 19th century, and combining it with '-like' is a recent development to describe things reminiscent of the United States.

Initially, '-like' was used with nouns to mean 'similar to' that noun. In 'US-like', it means 'resembling the United States'.
