'antibody-like' is formed in English by combining 'antibody' and the suffix '-like', where 'antibody' refers to a protein produced by the immune system and '-like' means 'resembling or similar to'.

'antibody-like' was created in modern English by combining the noun 'antibody' (first used in the late 19th century) with the suffix '-like', a common English suffix for forming adjectives meaning 'similar to'.

Initially, it meant 'having a resemblance to an antibody', and this meaning has remained consistent in scientific and medical contexts.
