'insect-related' originates from the combination of 'insect' and 'related', where 'insect' comes from Latin 'insectum', meaning 'cut into' and 'related' from Latin 'relatus', meaning 'brought back'.

'insectum' transformed into the French word 'insecte', and eventually became the modern English word 'insect'. 'Relatus' evolved into the English word 'related'.

Initially, 'insect' meant 'a small animal with a segmented body', and 'related' meant 'connected or associated'. The combined term 'insect-related' maintains this meaning of association with insects.
