'eco-focused' originates from a combination of the prefix 'eco-' and the adjective 'focused'. 'eco-' comes into English via New Latin from Greek 'oikos', where 'oikos' meant 'house' or 'household', and 'focused' derives from Latin 'focus', where 'focus' meant 'hearth' or 'center'.

'eco-' developed from Greek 'oikos' into New Latin and modern English prefixes such as 'eco-' (seen in words like 'ecology' and 'economy'), while 'focus' passed from Latin into scientific and general English use; the past-participial/adjectival form 'focused' arose in modern English to mean 'directed attention', and the compound 'eco-focused' is a recent English formation combining these elements to mean attention directed toward ecological matters.

Initially, the roots referred to 'household' and 'hearth/center', but over time 'eco-' came to signal 'environment' or 'ecology' and 'focused' came to mean 'having attention or emphasis', so the combined term now means 'having attention or emphasis on environmental concerns'.
