How to Pronounce Diagram
"The scientist sketched a diagram showing the circuit connections."
"In the textbook, a flow diagram traces the steps of the experiment."
"She created a diagram to illustrate the organizational chart for the team."
Diagram is /ˈdaɪ.əˌɡram/ in most varieties of English. The primary stress is on the first syllable: DIA-gram, with a light, unstressed second syllable /ə/. The final syllable ends with /ɡram/, where the 'gram' is pronounced as /gram/ with a hard /g/ and /ræm/ as in 'gram' not 'grame'. Listen to a standard pronunciation and note the tiny schwa in the second syllable: /ˈdaɪ.əˌɡræm/.
Common mistakes include under-emphasizing the primary stress on DIA, and mispronouncing the second syllable as /ɡrɛm/ or /ɡreɪm/. Also some speakers say /ˈdaɪˌæɡræm/ or /ˈdaɪəˌɡræm/. To correct: keep the primary stress on the first syllable and ensure the second syllable remains a light /ə/; pronounce /ɡræm/ clearly with a voiced /g/ and short /æ/. Slow practice bridges quick speech.
Across US, UK, and AU, the word retains /ˈdaɪ.əˌɡræm/ with primary stress on DIA. In most US and UK varieties, the /ɪ/ or /aɪ/ vowel in the first syllable is a diphthong /aɪ/. AU English generally aligns with rhoticity in connected speech but maintains the same IPA form for careful dictation: /ˈdaɪ.əˌɡræm/. The main differences occur in rhythm and vowel quality rather than the core IPA.
The difficulty lies in the two-part rhythm: a strong primary stress on DIA followed by a light, unstressed ə in the second syllable, then a tremulous /ɡræm/ final cluster. Beginners often blend /ˈdaɪ.ə/ as /ˈdaɪeɪ/ or drop the third sound entirely. Focus on keeping the /ɡ/ sound momentary and the /ə/ as a neutral, quick vowel. Practicing slow, deliberate enunciation helps with natural speed.
There are no silent letters in Diagram. All letters contribute to the sounds: D /d/, i /aɪ/ as a diphthong, a schwa /ə/ in the second syllable, and /ɡram/ with a hard /g/ and final /m/. The 'i' after the D participates in the /aɪ/ diphthong, not a silent letter. The word is fully phonemic in standard pronunciation.

US: maintain rhotic clarity only if connected speech; the word itself stays /ˈdaɪ.əˌɡræm/. UK: keep the same IPA; you may hear slightly crisper /æ/ in some regions. AU: similar to US/UK, with potential subtle vowel merging in rapid speech. Vowel notes: DIA /ˈdaɪ/ has the ʌɪ-trajectory of 'die'; second syllable /ə/ is a neutral vowel; final /æ/ is near-trap-bath boundary in some accents. Reference IPA when training, and practice with minimal pairs to feel the vowel differences.
Diagram comes from the Late Latin diagramma, which itself derives from the Greek diagramma, meaning 'a figure, figure drawn or written' from dia- ‘across’ + graphein ‘to write’. The term entered English in the 16th century to denote a figure or outline representing data or relationships. Over time, its usage broadened from mathematical and geometric sketches to include schematic representations in science, engineering, and information design. The core sense emphasizes a visual representation that clarifies connections, processes, or structures. First known English uses appear in scholarly and technical writings of the Renaissance, where diagrams accompanied complex arguments or experimental setups, signaling a shift toward communicating through intelligible visuals alongside text.
