Do 気が付く{つく} and 気[付く]{づく} have the same meaning?


Do 気が付く{つく} and 気[付く]{づく} have the same meaning?

If they both mean the same, is the が optional?




気が付く has three meanings.

  1. notice, realize
  2. (often in the form よく気が付く) be attentive, be quick to notice
  3. come to oneself (usually after losing consciousness)

For senses 1 and 3, 気付く is also used. When used in these senses, I do not
think that there is any difference in meaning between 気が付く and 気付く. I do not
recognize any difference in formality, either, but I may be wrong.
