The /n/ sound is spelled with <n> or <nn>. The /l/ sound is spelled with <l>. Notice how the homograph lead pairs with need and Ned.
This is a contrast between a lateral and and a nasal continuant, both in the alveolar region and both voiced. It is a known problem for speakers of Chinese and Thai, especially in syllable-final position.
Taboo word pairs include coon/cool and cunt/cult.

cannery calorie
consternation constellation
coronation correlation
darning darling
driven drivel
energy elegy
gerund Gerald
hornier haulier
Koran chorale
Natalie latterly
naughtiness nautilus
