The term 'mite-increasing' is a compound word formed from 'mite' and 'increasing'. 'Mite' originates from Old English 'mīte', referring to a small insect, while 'increasing' comes from the Latin 'increscere', meaning 'to grow'.

'Mite' has been used in English since the Old English period, while 'increasing' evolved from the Latin 'increscere' through Middle English 'increcen'.

Initially, 'mite' referred to any small creature, but over time it became more specific to certain arachnids. 'Increasing' has consistently meant 'growing or becoming larger'.
