Stress falls on the first syllable of each word: LY-ken PLAY-nus. In IPA: US/UK/AU /ˈlaɪ.kən ˈpleɪ.nəs/. The first word begins with the /l/ plus /aɪ/ vowel, followed by a schwa-like or reduced /ə/ in casual speech; the second word emphasizes the /eɪ/ in plan-, with final /nəs/. Visualize a two-beat phrase: LY-kən, PLAY-nəs. Audio resources can reinforce the two-stress pattern.
Common errors: misplacing stress by saying LY-chean or LY-chin for first word; mispronouncing planus as pla-NUS with excessive emphasis on the final syllable; conflating lichen with ‘lichen’ as a botanical term; saying planus with a hard 'a' or unclear final /əs/. Correction: keep /ˈlaɪ.kən/ with /ˈpleɪ.nəs/, ensure final syllable reduction is light: /ˈlaɪ.kən ˈpleɪ.nəs/.
In US/UK/AU, the core sounds are similar, but rhoticity affects the first word: US typically rhotic in /ˈlaɪ.kən/ with a rhotic /ɹ/ only if speakers link after a vowel; UK often non-rhotic, but /ˈlaɪ.kən/ remains similar; AU tends to similar to UK, with slight vowel shifts (/aɪ/ vs /aːɪ/ depending on speaker). The second word /ˈpleɪ.nəs/ keeps /eɪ/ vowel; rhotics influence only if followed by a vowel in connected speech.
It combines a two-word medical term with a Latin/Greek matrix: 'lichen' is not pronounced like the animal lichens or the skin’s lichen line; 'planus' ends with a soft 's' like /s/ but often reduced. The main challenge is maintaining two-stress pattern and accurate /ˈlaɪ.kən/ versus the notional 'lie-chen' mispronunciation, plus avoiding a heavy final syllable on planus. Focus on correct vowel qualities and final /əs/ vs /əs/.

US: rhotic accent, pronounce /ˈlaɪ.kən ˈpleɪ.nəs/ with clear /r/ only in linking cases; UK/AU: typically non-rhotic; the first syllable carries the primary vowel length, while stress remains on the first syllable of each word. Vowel quality: /aɪ/ as in 'eye', /ə/ mid-central vowel in the second syllable of lichen; AU tends to slightly wider diphthongs in /pleɪ/ and /ə/. IPA references: /ˈlaɪ.kən ˈpleɪ.nəs/.
Lichen planus derives from the Greek word lichen meaning a plant-like growth or moss, likened to the rough, flat-topped papules of the skin. Planus comes from Latin planus meaning flat, level, or plain, reflecting the flat-topped appearance of lesions. The English medical usage emerged in the 19th century as clinicians described a distinctive dermatitis with a lichen-like rash. The term lichen itself historically covered a range of dermatologic descriptions; later refinements narrowed to a chronic inflammatory disease affecting skin and mucosa. First known medical writings using the term appeared in dermatology texts mid-1800s to early 1900s, with continued evolution as our understanding of mucosal variants and autoimmune associations expanded.
