Expressing past states, actions, and conditions accurately is essential for clear communication in English. One common situation is describing when someone was busy—whether explaining why you couldn’t answer a call, narrating a story, or detailing your past schedule. But since ‘busy’ is primarily an adjective, not a verb, many learners are unsure how to express its “past tense.”
This confusion arises because adjectives like ‘busy’ don’t change form to indicate tense. Instead, we use linking verbs such as ‘was’ or ‘were’ (past tense forms of be) combined with the adjective. Sometimes, we extend this with continuous or perfect tenses to add nuance or indicate timing.
Understanding how to convey being “busy” in the past is crucial for effective storytelling, polite explanations, and accurate tense consistency in writing and speech. This comprehensive guide is designed for English learners, teachers, writers, and anyone who wants to master how to express past states with adjectives like “busy.”
You’ll learn definitions, grammatical structures, clear examples, essential rules, common mistakes, practice exercises with answers, and advanced nuances such as reported speech and idioms. By the end, you’ll confidently express all shades of past busyness in English!

3. Definition Section
3.1. What Does “Busy” Mean?
Busy is an adjective meaning someone is actively engaged, occupied, or involved in activity. According to major dictionaries:
- Cambridge Dictionary: actively doing something, especially work or a particular activity.
- Oxford Dictionary: having a lot to do; occupied with tasks or work.
“Busy” usually describes a temporary state, such as someone occupied at a particular moment or period, though in some contexts it can suggest a generally active lifestyle.
Present tense examples:
- I am busy with my assignments.
- She is busy preparing lunch.
- They are busy at work today.
- We are busy organizing the event.
3.2. Grammatical Classification
Busy is an adjective, not a verb. It describes the condition or state of a noun (person or thing). To express when someone was busy, you need a linking verb—primarily forms of be (am, is, are, was, were).
This means that to indicate past tense, busy itself doesn’t change, but the verb be changes to reflect the time.
3.3. What is the “Past Tense of Busy”?
Since busy is an adjective, it doesn’t have a past tense form like verbs do. Instead, you create the past tense by changing the linking verb to its past form:
- Simple past: was/were busy
- Past continuous: was/were busy + verb-ing (e.g., was busy studying)
- Past perfect: had been busy
This allows you to show different timings and aspects related to the state of being busy.
3.4. Usage Contexts
You express someone was busy to:
- Explain past unavailability: “Sorry, I was busy yesterday.”
- Describe past ongoing activity: “They were busy setting up the room.”
- Indicate a state before another event: “She had been busy before the meeting.”
Contrast with:
- Present: “I am busy now.”
- Future: “I will be busy tomorrow.”
Examples contrasting tenses:
- I was busy last night. (past)
- I am busy right now. (present)
- I will be busy later today. (future)
- They were busy studying when I arrived. (past continuous)
- She had been busy earlier that day. (past perfect)
