/l/ vs /r/: light vs right
In short
The /l/ vs /r/ contrast carries pairs like long/wrong, collect/correct and glass/grass. For speakers of Japanese, Korean and some Chinese varieties it is the single highest-impact consonant contrast to master. This contrast carries a HIGH functional load, confusing these two sounds frequently turns one real word into another, which is what actually damages intelligibility (Munro & Derwing 2006 found one high-load error hurts comprehensibility more than three low-load errors combined).
How to hear (and make) the difference
For /l/ the tongue tip firmly TOUCHES the ridge behind your teeth; for /r/ it curls up and touches NOTHING while the lips round slightly. Touch vs no-touch is the whole difference.
Most challenging for Japanese, Korean, Mandarin, Thai, Vietnamese speakers.
