forthrightly

The word 'forthrightly' is built from two ancient directional concepts. 'Forth', from Proto-Germanic, carries the sense of moving forward or onward, while 'right', from Proto-Indo-European reg- (to move in a straight line), denotes straightness and directness. Combined in Middle English as the adjective 'forthright', they literally described a path or course that goes straight forward. The adverbial suffix '-ly', of Germanic origin, was then added. Thus, the modern abstract meaning of speaking or acting in a direct, straightforward, and unambiguous manner evolved from this literal image of proceeding on a straight path without deviation.

Structure: forth (forward) + right (straight) + ly (adverb suffix) - forth: From Old English 'forþ', meaning forward, onward. It functions as an adverb indicating direction. - right: From Old English 'riht', meaning straight, direct, correct. It functions as an adjective/adverb indicating direction or manner. - ly: From Old English '-līce', an adverbial suffix forming adverbs from adjectives.
