Frequently asked questions
Which topic options does this tool cover?
5: Articles, Prepositions, Jumbled sentences, Punctuation, Subject-verb agreement. Pick one at the top of the tool; the page link updates (for example ?v=articles) so you can bookmark or share that exact view.
When do you use 'a' and when do you use 'an'?
It depends on the sound that follows, not the letter: an goes before a vowel sound and a before a consonant sound. That gives an hour and an MP because the h is silent and M is said 'em', but a university and a one-way street because those start with 'yoo' and 'w' sounds.
When do you use in, on and at for time?
At goes with clock times and points (at 7 o'clock, at noon, at night), on goes with days and dates (on Monday, on 12 March), and in goes with anything longer — months, seasons, years, centuries and parts of the day (in July, in 1998, in the morning).
How do you solve a jumbled sentence question?
Find the verb first, then the subject that agrees with it, and build outward: subject, verb, object, then place adverbs and prepositional phrases. Words like 'not only', 'no sooner', 'neither' and 'if' signal a fixed pattern, so anchoring those first usually settles the rest of the order.
What is a comma splice?
A comma splice is two independent clauses joined by only a comma, as in 'It rained all night, the match was cancelled.' There are three standard fixes: replace the comma with a semicolon, break it into two sentences, or add a coordinating conjunction after the comma ('It rained all night, so the match was cancelled').
Is it 'the box of chocolates is' or 'are'?
It is 'is'. The subject is box, which is singular; 'of chocolates' is a prepositional phrase and prepositional phrases never change the number of the verb. The same rule gives 'the list of items has been sent' and 'one of my friends is a doctor'.
