2 syllables: Lig, ands. Stress on Lig.
LIG-uhndz
/ˈlɪɡəndz/
Ligands is pronounced LIG-uhndz (/ˈlɪɡəndz/). It has two syllables (Lig-ands), with the stress on "Lig". Ligands are atoms, ions, or molecules that bind to another (usually larger) molecule, forming a complex. In chemistry and biochemistry, ligands attach to a central metal atom or a receptor, influencing reactivity or signaling. The term covers diverse binding partners, including neutral molecules and charged ions, and is central to catalysis, coordination chemistry, and pharmacology.

"The study compared how different ligands affect the catalytic activity of the metal center."
"Biochemistry researchers identified several ligands that bind to the receptor with high specificity."
"Metal-organic frameworks rely on rigid ligands to connect metal nodes into porous networks."
Pronounce as LI-gən-dz or LI-gands (US/UK). Primary stress on the first syllable: /ˈlɪɡ.əndz/ in US and UK variants. The middle syllable uses a schwa /ə/ and the final is a voiced alveolar affricate cluster /ndz/, which can reduce to /ndz/ in fluent speech. An audio reference: listen for the clear initial /l/ with front vowel, followed by a light /ɡ/ and an unstressed /ə/ before /ndz/.
Two common errors: (1) misplacing the stress on the second syllable, saying li-GANDS; (2) pronouncing the final /dz/ as a hard /z/ or dropping the /d/ in /ndz/ cluster, saying /ˈlɪɡ.ənz/. Correction: keep primary stress on LI-, insert a genuine /d/ before the /z/ sound, and lightly voice the /d/ to blend into /ndz/ as /ndz/.
In US and UK, both use /ˈlɪɡ.əndz/ with rhoticity affecting only postvocalic r; ligands has no r anyway. AU tends to keep a very clear /ɡ/ and a slightly sharper /ɪ/; some Australians may lightly reduce the middle vowel to a near-schwa, producing /ˈlɪɡ.əndz/ with a brisk tempo. The differences are subtle; focus on early short /ɪ/ vs /iː/ and the smooth /ndz/ ending.
Two main challenges: the /ɡ/ before a vowel can cluster with /ɡ.əndz/; the /nd/ followed by /z/ creates a tight dental-alveolar transition. Also, the middle /i/ varies in fast speech, sometimes sounding like /ɪ/ or a reduced /ə/. Practice by isolating the /ɡ/ onset, then smoothly connect to /əndz/ with a light tongue contact, ensuring the final /dz/ doesn’t become a plain /z/.
Note the plural ending /-ɪdz/ or /-əndz/: in careful speech, you can hear a light /ɪ/ before the /dz/ in some speakers, giving /-ɪdz/ versus a stronger /-əndz/. The presence of /ɡ/ in the onset yields a consonant cluster LI- with /ɡ/; avoid doubling the /ɡ/ or flattening into /lɪ-ɡɚndz/. In careful enunciation, emphasize the /ɡ/ and the /nd/ cluster to prevent misreading as 'ligands' with a /ŋ/ or /l/ alt sounds.

Ligand comes from the late 19th century chemistry terminology, derived from the Latin ligare, meaning to bind or tie. The unhelpful but common root is ligare, which spawned various forms in scientific language. The term began to appear in chemistry texts as researchers described species that could bond to a central atom, especially in coordination chemistry and organometallics. Early usage was in German and French scientific literature, with English adoption increasing in the early 20th century as theories of complex formation solidified. Over time, ligands became generalized beyond metals to any binding partner in molecular recognition contexts, including biochemistry where ligands bind receptors or enzymes. Today, ligands are fundamental to understanding reaction mechanisms, catalysis, and drug-target interactions, and appear in diverse areas from materials science to medicinal chemistry.
