The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
The four present tenses
Present simple (I write) states facts, habits and permanent truths: "She teaches at the university." Present continuous (I am writing) describes action happening at or around the moment of speaking: "She is writing a report right now." Present perfect (I have written) connects a past action to the present, often without specifying when: "She has published three articles." Present perfect continuous (I have been writing) stresses the duration of an activity that started in the past and continues or has just stopped: "She has been writing since nine o'clock." These four forms cover almost every present-tense function in English academic and professional writing.
The four past tenses
Past simple (I wrote) expresses a completed action at a specific time in the past: "The committee approved the proposal in 2021." Past continuous (I was writing) describes an action in progress at a past moment, often interrupted: "She was reviewing the draft when the editor called." Past perfect (I had written) places one past action before another, marking the earlier one: "By the time the deadline arrived, she had revised the paper twice." Past perfect continuous (I had been writing) emphasises the duration of an activity that was ongoing before another past event: "She had been working on the manuscript for two years before it was accepted." These tenses allow precise narrative sequencing.
The four future tenses
Future simple (I will write) makes predictions or states intentions: "The journal will publish results in June." Future continuous (I will be writing) describes an action in progress at a future moment: "This time tomorrow she will be presenting her findings." Future perfect (I will have written) states that an action will be complete before a future reference point: "By Friday she will have submitted all sections." Future perfect continuous (I will have been writing) stresses the duration of an ongoing future activity: "By next year she will have been researching this topic for a decade." Together these four tenses handle all future-time distinctions.
Key facts
At a glance
- Total count: 12 tenses = 3 time frames × 4 aspects
- Simple aspect: completed facts, habits or states (writes / wrote / will write)
- Continuous aspect: action in progress at a point in time (is writing / was writing / will be writing)
- Perfect aspect: links two time points (has written / had written / will have written)
- Perfect continuous: duration up to a reference point (has been writing / had been writing / will have been writing)
- Key auxiliaries: be (for continuous), have (for perfect), will (for future)
- Academic note: academic English favours present perfect and past simple for reporting findings
Common misconceptions
What people often get wrong
Often heard: English has only three tenses: past, present and future.
Actually: English has 12 distinct tenses. The three time frames each combine with four aspects (simple, continuous, perfect, perfect continuous), giving 12 forms with different structural formulas and meanings.
Often heard: The present continuous can replace the present simple in all situations.
Actually: Present simple is used for habits, facts and permanent states; present continuous is for temporary, ongoing actions. "She works in research" (habitual) differs fundamentally from "she is working on a grant" (current activity).
Often heard: "Will" is the only way to express future time in English.
Actually: Future time can also be expressed with present continuous ("she is presenting tomorrow"), present simple for schedules ("the train leaves at 09:00"), and going to for plans or predictions based on evidence.
Common questions
FAQ
What are the 12 verb tenses in English?+
The 12 tenses are: present simple, present continuous, present perfect, present perfect continuous; past simple, past continuous, past perfect, past perfect continuous; future simple, future continuous, future perfect, and future perfect continuous. Each combines a time frame with an aspect to convey a distinct relationship between time and the action or state described.
Which tense should I use in academic writing?+
Academic writing typically uses present simple for established facts ("water boils at 100 °C"), past simple for reporting specific study results ("the participants completed the survey"), and present perfect for recent or ongoing relevance ("researchers have shown"). Consistency within a section is essential; tense shifts confuse readers and signal imprecision.
What is the difference between past simple and present perfect?+
Past simple reports a completed action at a definite past time: "She submitted the paper last Tuesday." Present perfect connects a past action to the present without specifying exactly when: "She has submitted the paper." Use past simple with time expressions (yesterday, in 2020); use present perfect with words like just, already, yet, ever and recently.
