Verbos con cambio ortográfico g>gu (presente subjuntivo)

Stem-changing Spanish g>gu verbs in the present subjunctive

Spanish verbs that end in -gar switch the -g for a -gu in all forms in the present subjunctive. Like most stem-changing verbs, this is to preserve the pronounciation from the infinitive.
For example:
llegar (to arrive) 
yo llegue
tú llegues
él llegue
nosotros lleguemos
vosotros lleguéis
ellos lleguen
