Underline is pronounced with the primary stress on the second syllable: un-der-LINE. In IPA for US: /ʌn.dɚˈlaɪn/, UK: /ˌʌn.dəˈlaɪn/, AU: /ˌʌn.dəˈlaɪn/. Start with /ʌn/ (like
Common mistakes include stressing the first syllable instead of the final, mispronouncing the /ɚ/ as a full /ər/ without rhotic quality, and blending /d/ + /ɚ/ too loosely. Correct approach: ensure secondary syllable /dɚ/ has a quick, rounded mid-central vowel with rhotic color if applicable in US; then clearly release /laɪn/ with a long diphthong /aɪ/. Practicing by isolating /dɚ/ as a brief schwa+r and then linking to /laɪn/ helps.
US tends toward rhotic pronunciation with /ɚ/ in /dɚ/ and a clear /laɪn/ with a strong /r/ coloring in connected speech. UK typically features non-rhotic /ˈʌn.də.laɪn/ with a less pronounced rhotic vowel and a shorter /ɪ/ in unstressed syllables. Australian often shows a reduced /də/ and a broad /laɪn/ but can maintain some non-rhoticity in careful speech. In all, the final /laɪn/ is a relaxed diphthong; the main variation is in the middle /dɚ/ vs /də/ and how rhotic or non-rhotic the r is in connected speech.
The challenge lies in smoothly linking the alveolar /d/ to the rhotacized schwa /ɚ/ (US) or /ə/ (UK/AU) and then transitioning into the elongated /laɪn/. The sequence /n.d/ can cluster and produce a slight nasal release clash, especially in rapid speech. Also, the two-stressed word boundary in the final syllable requires precise timing to avoid truncating the /laɪn/.
A distinctive feature is the strong final diphthong in /laɪn/, which carries the primary stress; the middle /lə/ or /dɚ/ portion is less prominent but crucial for naturalness. The word’s rhythm is heel-toe style: unstressed first syllable, slightly reduced second, stressed final. Attention to the /laɪn/ glide and proper linking from the /d/ into the /l/ can help beginners avoid monotone or clipped endings.

Underline originates from the combination of under + line. The concept of drawing a line beneath text for emphasis was established in printing and handwriting practices centuries ago, evolving with typography. The term underline appeared in English in the late 16th to early 17th century, aligning with similar emphasis marks such as italics and bolding developed in printing. The word conveys a literal physical action—placing a line under a line of text—to signal importance, annotation, or instruction. Historically, underlining rose to prominence in manuscripts, early typewriting, and eventually digital formats where it is commonly used in word processors and emails. First known uses appear in English print as a descriptive action in manuals and guides about formatting, with “underline” documented in dictionaries by the 18th century as a verb and by the 19th century as a noun, reflecting both the mark and the act. Over time, the meaning broadened to include metaphorical emphasis and even titles of albums or sections that use underlining as a design feature. The term remains tied to its tactile, visual cue—the simple underline beneath text signaling importance, separation, or focus.
