The word 'straitened' originates from the adjective 'strait', which entered English via Old French from the Latin 'strictus', meaning "drawn tight" or "compressed". The verb-forming suffix '-en' was added to create 'straiten', meaning "to make narrow or tight". The past participle form '-ed' then transformed it into an adjective describing the resulting state. Thus, the literal sense of being made narrow evolved metaphorically to describe circumstances that are financially constricted or limited, moving from a physical to a socio-economic condition.
