Let me think
A short, honest pause. You're choosing your answer and it'll come in a second or two.
Examples
Let me think... probably summer, because I love being outside.
Hmm, let me think. I'd probably pick the beach over the mountains.
In a conversation
A: What's your favourite season?
B: Let me think... autumn, I think. It's not too hot and the evenings are lovely.
Common mistake
Not: What is my favourite season? My favourite season is autumn.
Say: Let me think... autumn, I think.
Repeating the question word for word sounds like stalling. A short pause phrase sounds natural and gets you going.
