Expert writing Tips
Best practice
Use "I'd always assumed" when you want to establish a 'before' and 'after' narrative. It is most effective when followed by a conjunction like 'but' or 'until' to introduce a new discovery.
Common error
Do not confuse the past perfect 'I'd' (I had) with the conditional 'I'd' (I would) in this context. While "I'd always assumed" refers to a past belief, 'I would always assume' refers to a habitual action. Always ensure the verb 'assumed' remains in the past participle form.
