lengthening

the word 'lengthening' is built upon the old english noun 'length', which itself derives from the adjective 'long'. the suffix '-en' was attached to nouns and adjectives to form verbs meaning "to make or become", creating the verb 'lengthen'. finally, the gerund or present participle suffix '-ing' is added to form a noun that denotes the action or process of the verb. thus, the word's construction follows a clear and logical sequence from the core concept of linear extent ('long') to the process of making that extent greater.

Structure: length (noun) + en (verb suffix) + ing (noun suffix) length (from old english lengþu, meaning "property of being long", a noun-forming suffix added to an adjective); en (from old english -nian, a verb-forming suffix meaning "to make or become"); ing (from old english -ung, -ing, a noun-forming suffix denoting an action or its result).
