This term is used independently, not directly modifying a noun. It is always preceded by the particle a.

"Fourteen" directly modifying a noun is indicated by cheithre before the noun (and triggering lenition on it) and déag after it.

• ceithre bhus déag ― fourteen buses
• deich a ceithre bhus ― fourteen buses

The form aon deich a ceathair was prescribed by Peadar Ua Laoghaire in the 1920s, but it is unclear whether it has ever been used by native speakers.
