Errores frecuentes
Olvidar la -s de la tercera persona: He fail en vez de He fails
Correcto: He/She/It fails
En el present simple, la tercera persona del singular (he/she/it) siempre añade -s o -es al verbo. Es el error más frecuente entre hispanohablantes.
Pronunciar la -ed como sílaba separada en todos los casos
Correcto: La -ed solo se pronuncia como sílaba extra (/ɪd/) tras t o d. Tras consonante sorda suena /t/, tras sonora /d/.
En español todas las sílabas se pronuncian, pero en inglés -ed no siempre es una sílaba: walked = /wɔːkt/ (una sílaba), wanted = /ˈwɒntɪd/ (dos sílabas).
Formar preguntas sin do/does: You fail? en vez de Do you fail?
Correcto: Do you fail? / Does he/she fail?
En español, la pregunta se forma con la entonación. En inglés, el present simple y past simple necesitan el auxiliar do/does/did para preguntas y negaciones.
Confundir present simple con present continuous: I fail vs I am failing
Correcto: Hábito/general → I fail | Ahora mismo → I am failing
El present simple se usa para hábitos y verdades generales, mientras que el present continuous se usa para acciones en progreso. En español a menudo se usa el mismo tiempo para ambos.
