4 syllables: Mo, no, a, mines. Stress on a.
moh-noh-AM-eenz
/ˌmoʊnoʊˈæmiːnz/
Monoamines is pronounced moh-noh-AM-eenz (/ˌmoʊnoʊˈæmiːnz/). It has four syllables (Mo-no-a-mines), with the stress on "a". Monoamines are a class of neurotransmitters derived from aromatic amino acids, including dopamine, norepinephrine, and serotonin. They play key roles in mood, arousal, and cognition. The term covers several related compounds produced in nerve cells and other tissues and is commonly discussed in neurochemistry and pharmacology contexts.

"Researchers measured monoamines in the brain to assess the effects of the drug treatment."
"The study focused on how monoamines influence reward and motivation pathways."
"Different antidepressants alter monoamine levels in the synaptic cleft."
Phonetically, say /ˌmoʊ.noʊˈæmiːnz/ in US English, with primary stress on the second 'a' in 'amines.' In careful speech: moh-NO-ah-MEENS, stressing the -am- portion, and making the ending -ines as /iːnz/. The first syllable is unstressed in many contexts, sounding like 'mo-,' the second stress falls on 'amine' as a syllable, and the final 'es' carries the /z/ or /s/ depending on liaison to the plural sound. If you listen to a video, you’ll hear a clear /ˌmoʊ.noʊˈæ.miːnz/ pattern.
Two frequent errors: (1) misplacing stress, saying MON-uh-AY-meenz or mo-NO-a-meenz; to fix, practice breaking the word into three metered syllables with the middle demanding primary stress. (2) mispronouncing 'amines' as 'a-meens' instead of 'uh-meenz' or as /æmiːnz/ vs /ˈæmɪnz/. Use slow, syllable-timed reading to keep the 'aa' sound long and the final /iːnz/ clear. Focus on the 'no' and 'amine' parts distinctly, not blending them.
In US English, you’ll hear /ˌmoʊ.noʊˈæ.miːnz/ with rhoticity and a clear /oʊ/ in first two syllables and a long /iː/ in 'amines.' UK English tends to reduce the first two vowels slightly: /ˌmɒ.nəˈæ.miːnz/ with less pronounced diphthongs and a more centralized schwa in some speakers. Australian English also uses /ˌmoːnəˈæːmiːnz/ with even more centralized vowel quality and a possibly shorter stress fall on the penultimate. The main differences revolve around vowel quality (rhotics, diphthongs) and the subtle reduction of the first vowels.
Three specific challenges: (1) the sequence /moʊ.noʊ/ blends two long vowels that can sound like one without clear break; pause briefly between 'mo' and 'no' to avoid a run-on. (2) the 'amine' nucleus /ˈæ.miːn/ requires keeping the long 'i' sound and ensuring the 'n' blends into the final 'z' plural; avoid epenthesis or turning /æmiːnz/ into /æmɪnz/. (3) plural ending /-nz/ can be mispronounced as /-nz/ or /-ns/; ensure a voiced alveolar nasal plus a voiced sibilant in the final syllable.
Yes. The natural pattern places primary stress on the third syllable: mo-no-AM-ines, with the 'AM' carrying the main emphasis. The initial syllables are lighter, sometimes nearly unstressed, especially in rapid speech. If you encounter a author-style pronunciation, you might also hear a flatter stress across the word, but the common medical and scientific usage uses the secondary-stress pattern on the second-to-last syllable.

Monoamine originates from combining the prefix mono- meaning 'one' or 'single' with the word amine, a basic organic compound derived from ammonia. The root amine itself traces to the French amine, from the German Aminal, ultimately from ammonia. In chemistry, monoamines refer to compounds containing a single amine group (-NH2 or similar) attached to an aromatic or aliphatic skeleton. In biology, the term extended to neurotransmitter families formed by decarboxylation or hydroxylation of amino acids, yielding substances like dopamine, norepinephrine, and serotonin. The usage emerged in mid-20th century pharmacology when scientists categorized neurotransmitters by functional group and origin, distinguishing monoamines from peptides and amino acid transmitters. First known written use in scientific texts appears in the 1950s as researchers described monoamine oxidase inhibitors and their effects on monoaminergic systems. Over time, the term broadened to cover broader neurotransmitter families (e.g., catecholamines as a subcategory), while in clinical contexts it remains a standard umbrella for amine-based signaling molecules critical to mood, motivation, and autonomic regulation.
