Learn an idiom as a complete expression and use the sentence around it to work out its meaning. Break the ice means make people feel more comfortable, under the weather means slightly ill, and hit the nail on the head means describe something exactly.
Do not choose a confusing word by sound alone. Ask what the sentence means, identify the word class it needs, and compare the pair in a complete sentence.
Choose a linker by asking what the second idea does. Use and for addition, but or however for contrast, because for a reason, so or therefore for a result, and although for an unexpected contrast.
Start with a suitable greeting, state your reason early, make your request with could, would, or please, and end with thanks and a closing. Keep the subject line and main request specific.
Choose a feeling word by asking what happened, what the person expected, and how strong the reaction is. Pair the word with a clear reason when that reason matters.
Use formal English for professional, official, or unfamiliar relationships. Use informal English with friends and people you know well. Choose polite, complete wording when the situation needs distance or care.
Use will for a decision or offer made now and for many predictions. Use be going to for a prior intention or evidence-based prediction. Use the present continuous for a personal arrangement, and the present simple for a timetable or schedule.
Use the form required by the word before it. Many verbs take a gerund, many take to plus the base verb, and a smaller group can take both forms with either a similar or a different meaning.
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.
