comprarlo

In a sentence

• Quiero comprarlo ahora mismo.

  I want to buy it right now.

  Here 'comprarlo' combines 'comprar' (to buy) with the pronoun 'lo' (it), formed to express the intention to purchase 'it', which could refer to a masculine singular object.

• Lo encontré en la tienda y decidí comprarlo.

  I found it in the store and decided to buy it.

  In this sentence, 'comprarlo' follows the verb 'decidí' (I decided) to continue with the action directed toward the masculine singular object.

• Si pudiera, trataría de comprarlo mañana.

  If I could, I would try to buy it tomorrow.

  'Comprarlo' here functions as an infinitive verb with an attached pronoun ('lo') to indicate the hypothetical action of buying the masculine singular object in a conditional clause.
