This is the 174th most frequent Italian word.
abbiamo
"Abbiamo" means "we have" in English.
In this sentence, 'abbiamo' functions as the first-person plural form of the verb 'avere' (to have) in the present tense, indicating possession.
Abbiamo un compito importante da svolgere.
We have an important task to accomplish.
In this example, 'abbiamo' is used in a common expression for describing a physical state, 'avere + cold (freddo)', which in Italian involves the verb 'avere' instead of 'to be'.
Abbiamo freddo, quindi accendiamo il riscaldamento.
We are cold, so we turn on the heating.
Here, 'abbiamo' is part of the compound past tense of 'parlare' (to speak). It serves as the auxiliary verb for the passato prossimo.
