- When English adapted Latin loanwords, spelling conventions varied, which is why some writers doubled the final consonant before adding “-es,” producing “focusses.”

My Memory Tricks and Tips

Memory Trick 1: One “S” for Simplicity
“Focus” already has one “s” just add “es.” One word, one extra letter, no doubling.
Memory Trick 2: Think “US” Not “UK”
If you’re unsure, default to American spelling rules, which never double the consonant.
Memory Trick 3: Compare with “Bus”
