'temperature-changing' originates from the combination of 'temperature' and 'changing', where 'temperature' comes from Latin 'temperatura', meaning 'a moderate state', and 'changing' is derived from Old French 'changier', meaning 'to alter'.

'temperature' evolved from the Latin 'temperatura' through Old French 'temperature', and 'changing' evolved from Old French 'changier' to the modern English 'change'.

Initially, 'temperature' referred to a moderate state, but now it refers to the degree of heat present in a substance or object. 'Changing' has retained its meaning of 'altering or modifying'.
