Student or Learner
Would someone tell me the differeneces between "actually" and "in fact."
I suppose the two have very similar meanings. They are both used when expressing a contradictory or unexpected opinion or correcting someone, according to the Oxford dictionary.
Are there any differences in the follow points?
・Are there any situation where one is not replaced by the other?
・Are there any differences in formality?
・Are they for written or spoken language?
Thank you in advance for your help.
They can be used in writing and speaking.
There is a subtle difference.
"Actually" is used more in speech. It tends to be used when the speaker has just thought of some further facts to strengthen their opinion. In writing, one should have thought of this beforehand, but in spontaneous writing, such in an exam essay, it's quite alright to use.
"In fact" can be used to introduce a thought that sums up the opinion well, that puts the finishing argument with a strong point. It is more usable in planned formal writing. In fact, I use it a lot - much more than "actually".
Of course, because the differences are subtle, these points only give a few differences in usage.
