Complete the sentence with the correct form of the verb in brackets: "The rumour ____ (spread) through the whole office before lunch yesterday."

Erklärung

Yesterday places the event in finished past time, so the past simple is needed, and this verb does not change its shape for the past. Spreaded is not an English word. Because the verb itself gives no signal, the time reference in the sentence is the only thing that marks the tense, which is what makes invariant verbs easy to misread.
