What does crankiest mean?
Crankiest is the superlative form of the informal adjective cranky, describing whoever or whatever is most irritable, ill-tempered, or difficult at a given moment. A sleep-deprived child before dinner might be called the crankiest member of the household, just as an aging car can be described as being at its crankiest on freezing mornings. The word carries a mildly humorous, affectionate connotation more often than a harsh one — it suggests transient grumpiness rather than deep malice — which makes it a favourite in family life, pet descriptions, and light journalism. A secondary, older sense of cranky means eccentric or whimsically peculiar, so crankiest can occasionally describe the most idiosyncratic ideas or characters, though this usage has faded. Derived from the noun crank, once meaning an eccentric person, and possibly ultimately related to the Dutch and German word for sick, crankiest remains a vivid, expressive way to single out peak grouchiness.

The word 'cranky' may trace back to the Dutch and German 'krank', meaning sick — so calling someone the crankiest in the room was once closer to diagnosing them than insulting them.

Etymology of crankiest
Crankiest derives from cranky, formed by adding the suffix -y to the noun crank, which in the 17th and 18th centuries could mean an eccentric or whimsical person. The ultimate origin of crank in this sense is uncertain, but it has been linked to the Dutch and German adjective krank, meaning sick or unwell, which would make those words its closest continental cognates. From the notion of eccentric temperament, cranky shifted toward its dominant modern sense of easily irritated or bad-tempered.
