The 'ZC' Spelling Change
For this verb, when you have a 'yo' form or a 'special form' (subjunctive) that ends in 'o' or 'a', the 'c' changes to 'zc' to keep the soft 's' or 'th' sound.
When to use 'se'
Use 'estremecerse' (with the extra 'se') when you are talking about a person shivering or shuddering on their own. Use 'estremecer' without 'se' when something else is doing the shaking.
Missing the 'Z'
Mistake: “Yo estremeco.”
Correction: Yo estremezco. (The 'z' is needed before the 'o' to maintain the correct pronunciation pattern.)
