linearise
|lin-e-ar-ise|
/ˈlɪn.i.əˌraɪz/
make into a line / render linear
Etymology
'linearise' originates from Modern English, formed by adding the verb-forming suffix '-ise' to 'linear'; 'linear' ultimately derives from Latin 'linearis', where 'linea' meant 'line'.
'linearise' developed from adjective 'linear' (from Latin 'linearis' via Middle English), with the productive suffix '-ise' (from French '-iser') producing the verb; thus 'linea' -> Latin 'linearis' -> Middle English 'linear' -> Modern English 'linearise'.
Initially related to the adjective sense 'of or relating to a line', the verbal form came to mean 'to make or treat as linear', and in technical usage it often specifically means 'to approximate by a linear function'.
