It is #EnigMarch, and each day the excellent EnigMarch people post a prompt word; then puzzle nerds try to design puzzles around that word. (Today's word is rule.)

Below are five words and five transformation rules. Each word becomes some other word (not listed below) when a transformation rule is applied. Unfortunately, I lost track of which rule goes with which word. I dare you to figure it out:

The words:

taped	→ _ _ _ _◯
fires	→ _◯_ _ _
waits	→ _ _ _◯_
flout	→ _ _◯_ _
pecan	→ ◯_ _ _ _

The rules:

Change vowels to be the same, e.g. SOLID becomes SALAD
Reorder letters alphabetically, e.g., LOYAL becomes ALLOY
Reverse the word, e.g. PARTS becomes STRAP
Shift each letter four ahead in the alphabet, e.g., BANJO becomes FERNS
Translate to Morse, reverse that, then translate back to English; e.g. REEDY becomes QUEER

When you're done, the circled letters should spell a rule of sorts: ◯◯◯◯◯
