Choose a preposition from the relationship in the sentence. Use at for a point, in for an enclosed space or longer period, on for a surface or day, by for a method or deadline, for for purpose or duration, and with for company or a tool.
A proverb gives a general observation or piece of advice in a fixed, memorable form. Treat it as one possible view, not as a rule that settles every situation. Use the surrounding conversation to work out what the speaker means.
Choose punctuation by the meaning and structure of the sentence. End a statement with a full stop and a direct question with a question mark. Use commas to separate items and to mark an opening phrase when it helps the reader see the main clause.
To assess your English fairly, choose one task that matters to you, complete it without help, then check it against a small set of clear criteria such as meaning, accuracy, and clarity.
Use slang carefully because its meaning and tone depend on context. It may suit a relaxed chat with people who know the expression. In a message to a teacher, customer, or new colleague, plain English is usually easier to understand.
For useful English speaking practice, answer the question directly, add one detail, and listen for a natural next question. Repeat short conversations so you can improve one part at a time.
Read the base word first, then use the suffix as a clue. Endings such as -ness and -ment often form nouns, -ful and -less often form adjectives, -ize often forms verbs, and -ly often forms adverbs.
Match the tag to the statement's auxiliary verb and subject. After a positive statement, use a negative tag: ‘The meeting starts at nine, doesn't it?’ After a negative statement, use a positive tag: ‘You aren't busy, are you?’
Learn each B word with a short context. Ask whether it names a thing, describes an advantage, or states an action. Then check which words usually appear with it.
Learn each C word with a short meaning, a common phrase, and a complete example. Use calm for a peaceful state, careful for attention to possible problems, cancel for ending a plan, capable for having an ability, compare for examining differences or similarities, and complain for saying that something is wrong.
