looked over her should (shoulder)

'I go to' and 'I went to' are short but signal different times: present/habitual vs past/completed. Use the present for routines and the past for actions tied to a specific time.

Below are quick checks, many concrete wrong/right pairs, rewrite templates, and context-specific examples for work, school, and casual speech so you can fix sentences immediately.

Quick answer - which to use

'I go to' = present simple (habit, general truth, or regular schedule). 'I went to' = past simple (a completed action at a specific past time).

If you can answer "When?" with a past word (yesterday, last week, in 2019), use 'went'.
If it describes a routine (every day, usually, often), use 'go'.
For planned near-future events, use 'I'm going to' or 'I will go', not plain 'I go to'.

Core explanation: present simple vs past simple

'I go' (present simple) names routines, repeated actions, or general facts: I go to work every day. 'I went' (past simple) reports a finished action and is usually anchored by a time: I went to work yesterday.

Present cue words: every day, usually, often, always, sometimes.
Past cue words: yesterday, last night/week/month/year, two days ago, in 2015.

Real usage and tone

Use 'go' for habits or facts and 'went' to move a narrative into the past or report finished events. In reports and formal writing, the wrong tense can misstate whether a task is complete.

Storytelling: keep verbs consistent in the past (I went, I saw, I met).
Reports/emails: use 'went' for completed visits, inspections, or meetings.
Habit example: I go to the gym every Monday. (present-regular)
Report example: I went to the client on Monday and we signed the agreement. (past-completed)

Common wrong patterns - copyable wrong/right pairs

When a past-time phrase appears, swap 'go' for 'went'. If you mean a routine, keep 'go' and remove past-time words.

Work examples (emails, reports, meeting notes)

At work, use 'went' for completed tasks and 'go' for standing procedures or habits. Mention dates when the action produced a result.

Wrong: I go to the client on Monday and delivered the contract.
Right: I went to the client on Monday and delivered the contract.
Wrong: I go to the site last week; the issue is fixed.
Right: I went to the site last week; the issue is fixed.
Wrong: I go to weekly status meetings and I update the tracker.
Right: I go to weekly status meetings and I update the tracker. (present-habit)

School examples (essays, lab reports, student talk)

Use past tense for completed experiments, trips, or assignments. Use present for course schedules or general facts. Keep tense consistent within a section describing a single experiment or event.

Wrong: I go to the lab yesterday and recorded the data.
Right: I went to the lab yesterday and recorded the data.
Wrong: I go to class every Tuesday when the seminar meets.
Right: I go to class every Tuesday when the seminar meets. (present-routine)
Wrong: I go on the field trip last month and collected samples.
Right: I went on the field trip last month and collected samples.

Test your sentence in context - the full sentence usually makes the tense obvious.

Casual speech examples (texts, social posts, conversations)

Casual language is forgiving, but tense mistakes still confuse. Keep past events in the past and add a time marker for clarity.

Wrong: I go to Sarah's party last night; it was fun.
Right: I went to Sarah's party last night; it was fun.
Wrong: I go to the gym an hour ago.
Right: I went to the gym an hour ago.
Wrong: I go to the store earlier and bought coffee.
Right: I went to the store earlier and bought coffee.

Rewrite help - fix your sentence in three quick steps

Use these checks and copyable rewrites to fix common mistakes fast.

Step 1: Look for a past-time word. If present, use 'went'.
Step 2: Decide habit (go) vs finished (went).
Step 3: If timing is unclear, add a time phrase or pick a clearer past verb (visited, attended).

Original: I go to the store yesterday.
Rewrite: I went to the store yesterday. Alternate: I visited the store yesterday.

Rewrite: I went to the training last Friday and learned new skills.

Memory tricks, hyphenation, spacing, and tiny formatting pitfalls

Quick trick: Ask "When?" If the answer is a past marker, use 'went'. If the answer is "every day" or "usually", use 'go'.

Hyphenation/spacing: 'I go to' and 'I went to' have no hyphens. Watch spaces around contractions and punctuation so words don't run together ('Iwent' is wrong).

Mini-test: Replace 'go' with 'went' and check compatibility with any time words you used.
Avoid informal shortcuts like 'gonna' in formal writing; use 'I'm going to' instead.
Formatting: Bad: 'Iwent to the store.' Good: 'I went to the store.'

Similar mistakes to watch for

These errors often occur alongside tense mistakes: present perfect vs past simple, 'am/are going to' vs plain present, and passive constructions.

'I have been to Paris' (present perfect for experience) vs 'I went to Paris in 2019' (past simple with a specific time).
'I'm going to London next week' is better than 'I go to London next week' for planned trips.
Use 'was/were going' for interrupted or in-progress past actions (I was going to the store when it started raining).

FAQ

When do I use 'I go to' instead of 'I went to'?

Use 'I go to' for routines and habitual actions (I go to work every day). Use 'I went to' for completed past actions, usually with a time reference (I went to work yesterday).

Is 'I go to the store yesterday' ever correct?

No. 'Yesterday' requires a past verb: I went to the store yesterday. Replace 'go' with 'went' when a past time is present.

How do I handle mixed sentences like 'I go to the meeting and we discussed the budget'?

Decide whether you're reporting a past meeting or describing a habit. If past: I went to the meeting and we discussed the budget. If habitual: I go to meetings and we discuss the budget.

What about future plans - can I use 'I go to'?

For future plans, avoid plain 'I go to'. Use 'I'm going to' or 'I will go' (I'm going to the concert next week). 'I go' can sound like a schedule and is often ambiguous.

Are there times when 'went' isn't enough - what about 'was going' or 'visited'?

Yes. Use 'was going' for interrupted or ongoing past actions and 'visited' or 'attended' when you want a more specific or formal past verb. Example: I was going to the office when the meeting started. vs I visited the office yesterday.
