| When an approximant articulation occurs at the same time as another articulation is being made at a different place in the vocal tract, the approximant is said to form a secondary articulation. |
| In clusters, the preaspiration merges with a preceding nasal or apical approximant, rendering them voiceless. |
| Dublin's retroflex approximant has no precedent outside of northern Ireland and is a genuine innovation of the past two decades. |
