Talk or Speak ?
Exemple : ‘’If you want more information then you should talk to my boss.’’
The verbs "talk" and "speak" are often mixed up as they have very similar meaning. "Talk" is generally less formal than "speak." It also places a greater focus upon the fact that both a speaker and a listener are present.
Exemple : ‘’Don't speak unless you are spoken to!’’
"Speak" is more formal and should be used in interviews, presentations and lectures. It is also particularly used in relation to languages; we "speak" a language but never "talk" a language. "Speak" also focuses upon the person saying the words and places little or no focus on the listener.
