Research involving stuttering in multilingual individuals is limited. Speech-language therapists face the challenge of treating a diverse client base, which includes multilingual individuals. The aim of this study was to examine the stuttering moments across English, Afrikaans, and German in a multilingual speaker. A single multilingual adult with a severe developmental stutter participated in this study. A mixed-method design was implemented. The results were perceptually analyzed, and interrater reliability was determined. The results revealed that the voiceless plosive [k], the voiceless fricative [f], and the plosive-lateral approximant cluster [kl] caused stuttering moments across the languages. More stuttering moments occurred on consonants as opposed to vowels. The most prominent core behavior was prolongations. Language proficiency plays a role in the increase of the moments of stuttering in the least proficient language. Future research on a larger sample size is recommended. Research on African language speaking multilingual person who stutters (PWS) should be pursued.
