How is the Greek letter "lambda" pronounced in code contexts?
The Greek letter lambda (λ) is pronounced 'LAM-da', /ˈlæm.də/, with stress on the first syllable and the 'b' essentially silent or very soft. In programming, 'lambda' means an anonymous function, and it is also the name of AWS Lambda. The first syllable has the short /æ/ vowel as in 'cat', and the ending '-da' reduces to a schwa. Do not over-pronounce the 'b'; the lips barely close. Say it confidently as two syllables: LAM-da.

How is the Greek letter "pi" said aloud in English tech contexts?
In English, the Greek letter pi (π) is pronounced 'pie', /paɪ/, with the /aɪ/ diphthong as in 'my'. It is the mathematical constant roughly 3.14159 and also names tools like the Raspberry Pi. Note that English speakers say 'pie' even though in Greek it is closer to 'pee'. For tech contexts, 'pie' is the standard. Be careful not to confuse it with other letter names; 'pi' always rhymes with 'high' and 'sky' in English-speaking engineering teams.

How is the prefix "micro" (from Greek "mu", µ) pronounced?
The prefix micro is pronounced 'MY-kroh', /ˈmaɪ.kroʊ/, with the /aɪ/ diphthong in the first syllable and the /oʊ/ glide in the second. It comes from the Greek 'mu' (µ), the symbol for 'micro-' meaning one millionth. You hear it in 'microservice', 'microsecond', and 'microcontroller'. Stress the first syllable strongly: MY. The symbol µ itself is read as 'micro' in measurements, for example 'µs' is 'microseconds'. Keep the opening vowel a clear gliding 'eye' sound, not a short 'i'.

How is the Greek letter "delta" pronounced, and what does it often mean in code?
The Greek letter delta (Δ or δ) is pronounced 'DEL-ta', /ˈdɛl.tə/, stressed on the first syllable with the /ɛ/ vowel as in 'bed' and a schwa ending. In programming and maths, 'delta' commonly means a difference or change between two values, as in 'the delta between versions'. You also see it in 'delta encoding' and version-control diffs. Say it as two clean syllables with the loud beat at the front. The ending '-ta' stays quiet and reduced.

How is the Greek letter "sigma" pronounced, and what does it often represent?
The Greek letter sigma (Σ or σ) is pronounced 'SIG-ma', /ˈsɪɡ.mə/, stressed on the first syllable with a hard /ɡ/ and a schwa ending. The capital Σ usually means summation (add everything up), while the lowercase σ often means standard deviation in statistics and machine learning. You meet it in data science and in 'six sigma' quality methods. Pronounce the 'g' clearly as a hard sound, not a 'j', and keep the loud beat on 'SIG' with a soft, reduced '-ma'.
