LAH-gur-ith-uhmz
/ˈlɑɡɚˌɪðəmz/
logarithms is pronounced LAH-gur-ith-uhmz (/ˈlɑɡɚˌɪðəmz/). Logarithms are mathematical functions that map a positive number to the exponent needed to produce that number as a power of a fixed base. They provide a way to reverse exponentiation, transforming multiplicative relationships into additive ones. In common usage, logarithms help solve growth, decay, and scale problems across science and engineering.

You say /ˈlɒɡəˌrɪð(ə)mz/ in US/UK spelling. Stress is on the first syllable: LOH-guh-rithmz. The sequence is heard as core 'log' with a soft schwa in the middle and a slight /ɪ/ in the second unstressed syllable before the final /mz/.
Common errors include over-emphasizing the second syllable, saying /ˈlɔɡəˌriːθɛmz/ or turning the final ‘th’ into a hard ‘t’ or ‘d’ sound. Another error is misplacing the /ɡ/ in ‘log-’: ensure the /ɡ/ is linked to the /ə/ with a brief, soft transition. Practice by articulating log- as one unit before the -arithms cluster.
In US, you’ll hear /ˈlɔːɡəˌrɪðəmz/ with a rhotic /ɹ/ and a clear /ɪ/ in the second syllable. UK tends to use /ˈlɒɡəˌrɪð(ə)mz/ with a shorter first vowel and more reduced final syllable. Australian often resembles UK but with a broader vowel quality in /ɒ/ and slightly more rounded /ɒ/; rhoticity varies regionally but is generally non-rhotic in some accents, affecting linking.
The difficulty lies in the multi-syllabic sequence /ˈlɒɡəˌrɪðəmz/ and the cluster -rithm-. The mid syllable uses a reduced vowel and the final -ms often devoices or links with a light /z/ or /s/. The tricky part is maintaining the correct order: log + a + rithms, without blending too early and without turning the th into a d or t.
The presence of the /ɹ/ sound after the first syllable and the /ð/ fricative in the second stressed syllable require precise tongue positioning: lips rounded, tongue blade high near the alveolar ridge for /ɹ/ before a central /ɪ/ vowel, and then the thin, dental /ð/ realization before /əmz/. This particular sequence makes the word feel longer and more complex than it looks.

The word logarithm originated in the early 17th century from the Greek roots logos (word, ratio, reason) and arithmos (number). The term was coined by John Napier, who introduced the concept in 1614 as a method to transform multiplicative relationships into additive ones via a “logarithm” statement. The idea built on earlier attempts to simplify calculations by using a sequence of numbers whose products or powers correspond to the original quantities. Napier’s logarithms were originally defined in a specific base (log base 10 in common usage later evolved) and were subsequently generalized by others to include natural logarithms (base e) and base-2 logarithms in computer science. The word “logarithm” entered mathematical vocabulary with the sense of a function or process that reduces complex calculations to simpler, linear-like steps. First known use is documented in Napier’s writings circa 1614-1619, where he described a table of logarithms to convert multiplication into addition, radically simplifying computation for astronomy and navigation. Over time, logarithms became foundational in fields ranging from pure mathematics to signal processing, chemistry, and data science, with the base choice (e, 10, 2) tailoring to domain conventions and computational convenience. The term’s connotation evolved from a computational device to a broader mathematical function, but the historical emphasis on reversing exponentiation remains central.
