Difference between "particularly" and "in particular"

Question

There are 2 sentences :

1. I particularly like the blue shirt.
2. In particular, I like the blue shirt.

As far as I understand they have different meanings. But there is one more example:

3. I like the blue shirt in particular.

Which of the first two sentences is the third one similar in meaning to?

Answer 1

Sentence (3) means the same as sentence (2) - that the speaker is singling out the blue shirt as a garment they especially like.
