What does dirtily mean?
Dirtily is an adverb formed from the adjective 'dirty', describing the manner in which something is done. It carries two main senses: a literal one, meaning in an unclean or soiled way (as when hands or clothes become begrimed through work or play), and a figurative one, meaning dishonestly, unfairly, or by underhanded methods — most commonly applied to competition, sport, politics, and business dealings. The figurative sense is by far the more frequent in modern usage; commentators might say a team 'played dirtily' to indicate fouls or unsporting conduct. Because English speakers often prefer phrasal alternatives such as 'in a dirty way' or simply describe the act itself, 'dirtily' remains relatively rare in everyday conversation and tends to appear in written commentary or formal description. It derives straightforwardly from Middle English 'dirty' plus the standard adverbial suffix '-ly', and it shares its roots with the noun 'dirt', which originally referred to excrement or filth before broadening to mean any unclean matter.
adverbIn a dirty manner; either literally, in a way that makes something unclean, or figuratively, in a dishonest, unfair, or underhanded way.
- In a physically unclean or soiled manner.
- In a morally corrupt, dishonest, or unfair manner; by foul means.
"The mechanic was accused of trading dirtily with the supplier."
"The children came in from the garden, their hands having been worked dirtily in the soil all afternoon."
"He fought dirtily, jabbing low when the referee wasn't looking."
Dirtily is one of those rare adverbs you almost never hear spoken aloud — yet it appears regularly in sports reporting whenever an athlete plays outside the rules.

Etymology of dirtily
Dirtily is formed within English from the adjective 'dirty', which emerged in late Middle English (around the 15th century) from the noun 'dirt' plus the suffix '-y'. The noun 'dirt' itself comes from Old Norse 'drit', meaning excrement, which entered English through Scandinavian influence during the medieval period. The adverbial suffix '-ly', derived from Old English '-līce', was appended to form 'dirtily', following the regular pattern of English adverb formation. Its closest relatives are therefore not foreign cognates but other English derivatives of 'dirt', such as 'dirtiness' and the verb phrase 'to dirty'.
How dirtily is actually used
