"You can add value to your house by extending or renovating it." I came across this phrase in Oxford dictionary. But I cannot really understand why the word "extend" is used here. Could you please explain what it means. Can we use the word expand here? Will there be any difference in meaning?
And another question: The company plans to extend its operations into Europe. The company plans to expand its market presence in Europe. What's the difference between these two phrases? Can we interchange the verbs extend and expand in these phrases?
