Notes on gender and number

The “o” ending is used by males when giving thanks, e.g. obrigado. Females use the “a” ending, e.g. obrigada. If you are saying thanks in the name of a group of males, a mixed sex group or a collective entity - like a corporation to a client: you use the “os” ending, e.g. obrigados. When you say thanks in the name a group of females, you use the “as” ending, e.g. obrigadas.
