Irregular Preterite Form
"Puse" is the simple past ('preterite') form of 'poner' for 'I'. It is highly irregular and does not follow the standard verb pattern. Memorize 'puse', 'pusiste', 'puso', etc., as a unit.
Not Using the Irregular Stem
Mistake: “Yo poní (Incorrect attempt to use imperfect or regular -er ending)”
Correction: Yo puse. (The stem changes completely from PONE- to PUS- in the simple past.)
meto
MEH-toh/ˈme.to/

Examples
Siempre meto las llaves en mi bolsillo trasero.
I always put the keys in my back pocket.
Meto la tarjeta en la ranura para pagar el peaje.
I insert the card into the slot to pay the toll.
The 'Yo' Form
'Meto' is the 'I' form of the verb 'meter' when you are describing a regular action happening right now or habitually.
Regular -ER Verb
'Meter' is a regular verb, meaning it follows the standard pattern for verbs that end in -er. This makes it easy to conjugate!
Meter vs. Poner
Mistake: “Using 'meter' when you mean 'poner' (general placement).”
Correction: Use 'meter' specifically when placing something *inside* a container or space. Use 'poner' for placing something *on* a surface or in a general location ('Pongo el libro en la mesa').
