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.
