The spelling of the word "gat after" can be confusing for some. The word is actually a contraction of "got after", meaning to pursue or chase. The "t" in "gat" is pronounced like a "d" due to a phonetic process called flapping. In IPA notation, the word would be transcribed as /ɡæd ˈæftɚ/. It's important to note that this type of contraction is common in some dialects of English, but may not be used universally.
