'statically-regulated' originates from the combination of 'static' and 'regulated'. 'Static' comes from the Greek word 'statikos', meaning 'causing to stand', and 'regulated' comes from the Latin word 'regulare', meaning 'to control or direct'.

'Static' evolved from the Greek 'statikos' through Latin 'staticus', and 'regulated' evolved from Latin 'regulare' through Old French 'reguler', eventually forming the modern English term 'statically-regulated'.

Initially, 'static' meant 'causing to stand', and 'regulated' meant 'to control or direct'. Over time, 'statically-regulated' came to mean 'controlled or maintained at a constant level'.
