Start with a simple description: name the symptom or situation, say when it began, and ask a direct question. Choose neutral words such as symptom, appointment, treatment, recover, and wellbeing when they fit the situation.
Read the whole sentence before choosing a form. Look for time words, the subject, countable nouns, and links such as because, although, and if. These clues usually narrow the choice.
Use a phrase such as I think or in my view, then give your main idea. Add because, for example, or a short explanation when your listener needs to understand your reason.
Make the receiver of the action the subject, then use the right tense of be with a past participle. Add by plus the doer only when the reader needs that information.
Use a prefix to add or change meaning before a base word, and a suffix to make a related form after it. Check both the meaning and the grammar of the finished word.
Use have or has plus a past participle when a past action has a connection with the present. Use the past simple when you say when a finished action happened.
Start complete sentences with a capital letter and end them with the punctuation that matches their purpose. Use commas to organise parts of a sentence, and use apostrophes carefully for possession and contractions.
Use said, told, asked, or another reporting verb, then choose the pattern that matches the original message. Reported statements use statement order, reported questions do not use question order, and reported instructions often use an object plus to and a verb.
First decide what job the missing word must do. Then choose the noun, verb, adjective, or adverb from the related word family that fits both the grammar and the meaning.
