Standard English permits only one modal per verb phrase, but certain dialects such as Southern American English and Scots allow two modals together, known as double modals, as in I might could go to the store later. They are non-standard in formal, written, and international English.
Grammar Rule
Standard English permits only one modal per verb phrase. Certain dialects (Southern American English, Scots, parts of the British Isles) allow two modals together, known as double modals, following consistent internal rules within those dialects. They are non-standard in formal, written, and international English.
Double Modals (Dialectal/Regional): Rules and Examples
| Dialectal form | Standard equivalent | Example |
|---|---|---|
| Might could | might be able to | I might could go to the store later. |
| Used to could | used to be able to | He used to could run five miles. |
Remember: Double modals are systematic, dialect-specific features, not learner errors — recognize them when you encounter them, but use single-modal forms in standard formal English.
