Conjugate stem changers in the present tense Grammar essential #28
Stem changing infinitives Stem changing infinitives are named for what they do– change in the stem. You are going to make some alteration of the stem before adding the verb endings. You will use the endings you already know. The hardest part of stem changers is knowing which ones change and which ones don’t.
Stem changers There are 4 different ways a stem changing infinitive can change (4 categories). The first is uue. It is the smallest category with only one infinitive jugar = to play (sports)
Jugar = to play (sports) Separate the stem and the infintive ending. Jug- is the stem Make the stem change uue The new stem is jueg- Put it in the conjugation box EXCEPT nosotros and vosotros. Nosotros and Vosotros do not make the stem change.
Jugar = to play sports Now just add the regular –ar endings.
Stem changers The second category is one of the largest. It is oue. Encontrar = to find is a stem changer. It is the same steps as jugar.
Encontrar = to find First separate the stem from the infinitive ending. Encontr- is the stem. Make the stem change oue New stem encuentr- Put into box– remember it will look like a shoe… they are called shoe verbs as well.
Stem changers The third category is again large. It is eie. perferir = to prefer is a stem changer. It is the same steps as jugar. *When there is more than one vowel that could possible make the change, choose the vowel closest to the verb ending.
Preferir = to prefer First separate the stem from the infinitive ending. prefer- is the stem. Make the stem change eie New stem prefier- Put into box– remember it will look like a shoe… they are called shoe verbs as well.
Stem changers The last category is a smaller one. It is ei. servir = to serve is a stem changer. It is the same steps as jugar.
servir = to serve First separate the stem from the infinitive ending. serv- is the stem. Make the stem change ei New stem sirv- Put into box– remember it will look like a shoe… they are called shoe verbs as well.
ei There are some rules that can help you distinguish between e i and e ie. In order to be e i, the infinitive must end in –ir. Now, that could be other categories as well, but –ar and –er cannot be e i . MR C VeSPeRS is also a way to help if you are needing a pneumonic device.
MR. C VeSPeRS M- medir (to measure) R – reír (to laugh) C – conseguir (To get/ to obtain) V – vestir(se) (to dress) S- servir (to serve) P – pedir (to ask for) R- repetir ( to repeat) S- seguir (to follow/ to continue)
