Our third and final guitar lesson with Cristhian from Colombia.

Carolina teaches about the apocopation, or shortening, of a small group of masculine singular adjectives in Spanish.

Having noticed a lot of confusion among her students regarding the usage and meaning of reflexive verbs and pronouns, Venezuelan Spanish teacher, Carolina Graterol, clarifies these topics with some useful examples.

Carolina gives us an in depth explanation of the verb "dar" (to give) in various contexts and sentences.

Teacher Carolina shares this lesson to help us differentiate between three Spanish verbs that have a very similar meaning.

Carolina teaches us the difference between the Spanish verbs "saber" and "conocer" [to know], which are similar but not interchangeable and used in different contexts.

Carolina, a Venezuelan Spanish teacher, teaches us the difference between the Spanish verbs, "mirar" (to look at/watch), "ver" (to see) and "buscar" (to look for) and gives us examples of sentences in which they might be found.

Because the Spanish words/expressions "haber" and "a ver" and "si" and "sí" sound exactly the same, their very different meanings are often confused. Spanish teacher Carolina enlightens us as to their differences.

Carolina teaches us how to correctly express "tonight" (esta noche) and "last night" (anoche) in Spanish and cautions us against some commonly used but erroneous expressions for these concepts.

Carolina teaches us about a few copulative conjunctions in Spanish and gives us examples.

Carolina teaches us about disjunctive and copulative conjunctions- ways to express "or" and "or else"- in Spanish.

Carolina explains some common errors she has noticed among her students in order to preclude us from making them ourselves.
