The 6 greatest dilemmas that cause 80% of mistakes for Spanish speakers — explained with clear pragmatic logic, Spanish interference warnings, and interactive discrimination quizzes.
Action is finished and belongs to a closed time window that has zero connection to right now.
I lived in Cartagena in 2021. (I don't live there now)
Ben bought a camera yesterday. (Specific finished moment)
Did you see Sofía this morning? (Said at 3:00 PM)
Present Perfect
Action connects to the present: either the time window is still open (today, this year) or it is an unfinished life experience.
I have lived here for 3 years. (I STILL live here today)
Kenji has visited London twice. (In his life so far)
Have you seen Sofía this morning? (Said at 10:00 AM)
⚠️ Hispanic Speaker Trap
In Spanish, we naturally say "Esta mañana me he tomado un café" or "Ayer he visto una película". In English, the moment you mention a finished time (yesterday, last week, ago, in 2020), Present Perfect is strictly forbidden. You must use Past Simple: "I saw a film yesterday".

Be Going To
Pre-meditated plans & intentions decided prior to speaking, or predictions based on current visual evidence.
Sofía bought tickets. She is going to fly to London.
Look at those black storm clouds! It is going to rain.
I am going to study Japanese next semester.
⚠️ Hispanic Speaker Trap
In Spanish, we use "voy a" for almost everything. When someone asks for help in a restaurant, a Spanish speaker might say "Wait, I am going to help you" (*sounds premeditated and weird). In English, an instant reaction MUST be "I will help you!" or "I'll carry that for you!".

Make money / friends / progress
DO (Actions & Obligations)
Used for tasks, jobs, duties, routines, and indefinite general actions with nothing created.
Do homework / chores / the dishes
Do business / research / an exercise
Do your best / a favor / nothing
⚠️ Hispanic Speaker Trap
Spanish has only one word for both: "Hacer" (Hacer la cama = Make the bed; Hacer la tarea = Do homework; Hacer un error = Make a mistake). Remember the rule of thumb: If you create or build something new, MAKE it; if you perform a routine task, DO it!

⚠️ Hispanic Speaker Trap
Spanish speakers frequently confuse "desde" (since) with "desde hace / por" (for). In English, never say "since 3 years" (*incorrect!). Say "for 3 years" (duration) or "since 2023" (starting point).
