niñita
/niˈɲita/ · B1 · noun · f
coward
niñita = niña (girl) + -ita (little): little girl, used as an insult
Niño is boy and niña is girl. The -ita ending makes it small: little girl. Calling a man a little girl is an old insult meaning he is weak or cowardly. The word is offensive, so recognise it but don't use it.
