For example.

Someone may know the correct word but still write ocassion without noticing.
Spell check usually catches the error but not everyone uses it.
Memory Tricks Can Be Hard
Some words simply need practice.
Since occasion has double c and one s many learners forget which letter is doubled.
That creates confusion between words.
Similar Pronunciation
The wrong spelling sounds almost identical to the correct spelling.
That makes the mistake even easier to miss.
