The 'Poner' Pattern
This verb is exactly like 'poner' (to put). If you know 'yo pongo' or 'yo puse', you simply add 'o-' to the front: 'yo opongo', 'yo opuse'.
Being Against Something
When you want to say you disagree with something, you must use the reflexive form (adding me, te, se) followed by the word 'a'. Example: 'Me opongo a la idea'.
Forget the 'a'
Mistake: “Me opongo el plan.”
Correction: Me opongo AL plan. Always use 'a' (which becomes 'al' with 'el') when mentioning what you oppose.
Using the wrong Past Participle
Mistake: “He oponido.”
Correction: He opuesto. Because it follows 'poner', the past form is irregular.
