Conjugations

Just remember in spanish that there are 3 types of regular verbs. They and in -ar -er and -ir.

usted and ustedes

In order to give and infermtive or negitive command in the usted or ustedes form you conjugate the verb into the present tense yo form. If the verb ends in -ar, add -e or -en. You add -e at the end if it is talking about one thing. You use -en if your talking about more than one. You add -a or -an for -er and/or -ir verbs. Once again add -a if its only talking about one thing and add -an if its talking about more than one. The same rules you use for tu commands apply also to usted and ustedes commands. For example, cortar goes to corte,and probar goes to prueben.

Impersonal Se

Referring to people in general in english is different than spanish. In spanish you use se+ a verb in the third person singular or plural. Just like with negitive tú commands we have to follow three steps. Step 1: Determine what verb you want to use. Step 2: Conjecgate the verb into the third person form based on if its singular or plural. Finally (step 3): Add se before the verb. For example: Se canta can mean any of the following.. They sing, you sing, one sings, and is sung.

negitive tú commands

Negitive tú commands are used to tell people to not do something. You dont just add the word no in front of a word. There actually four steps to form a negitive tú command. Make sure you follow these four steps. Step number 1: Figure out which verb you want to use. Step 2: Conjugate the verb into the yo form. Step 3: Drop the -o. Before moving on see if the verb ends in -ir, -er, or -ar. If he verb ends in -ar as -es at the end. If the verb ends in -er or -ir add -as. Step 4: After you figure out the ending just add no in front of the verb. Adding no in front of a verb is the same thing as saying do not. For example: Correr conjugate correr into corro, then drop the -o so it become corr. Then add -as to the end. Once your done with that just add no to the front and nor your saying don't run.
