keyboard capitalizes the P in pic even though I remove it every time it corrects me. I just want to type pic why is it capitalized

ebery time I type pic it corrects it like it's a name and i have to remove the word from known words every time but it adds it right back the next time i type Pic pic pic pic pic how do i stop it? I can't even add it to shortcuts like other common typos that don't get corrected because it's the same word
