Hogyan használjuk az "unless"-t
Az unless ugyanazt jelenti, mint az if...not. Az if-hez hasonlóan, az unless szót az egyszerű jelen vagy múlt követi, vagy a befejezett múlt idő (sosem a feltételes mód). Az unless szót az if...not helyett használjuk az összes fajta feltételes mondatban. A mellékmondatok sorrendje nem számít az olyan mondatokban, amelyekben az unless-t használjuk.
Feltételes mód I (type 1 conditional): Unless + egyszerű jelen (present tense)

|---|---|
| You will be sick if you don't stop eating. | You'll be sick unless you stop eating. |
| I won't pay if you don't provide the goods immediately. | I won't pay unless you provide the goods immediately. |
| If you don't study dilligently, you'll never understand trigonometry. | Unless you study dilligently, you'll never understand trigonometry. |
