analogous

Synonym discussion
Sense: adjective/1
All five words tell the reader that two things share features, but they sit at different points on the formality and precision scale. 'Similar' is the everyday word and the safest choice in conversation. 'Comparable' adds the idea that a comparison is fair or worth making, which is why it is common in reports and reviews. 'Analogous' is the most formal of the group; writers reach for it when they want to draw a careful, often technical, parallel between things from different categories — for example, 'the heart is analogous to a pump'. 'Parallel' suggests the features line up point by point, while 'akin' is more literary and feels closer to family resemblance, as in 'his mood was akin to grief'.

Etymology
English borrowed 'analogous' in the early 1600s from the Latin 'analogus', which itself came from Greek 'analogos', meaning 'in proportion' or 'according to a ratio'. The Greek word combined 'ana-' (meaning 'according to') with 'logos' (meaning 'word, reason, ratio'). The mathematical sense of matching ratios slowly widened, so today the word simply marks two things as comparable in some useful way.
