How to Pronounce Sisu is best understood on its own terms, away from the inspirational-poster noise. This page looks at the word from the ground up — what it actually names in Finnish daily life, what the research shows, and what it means in practice today. The goal is a clear, grounded answer you can actually use.
The correct pronunciation
Sisu is pronounced SEE-soo. The stress falls on the first syllable, which is short and firm. The second syllable is unstressed and shorter.
IPA and the common mistakes
In the International Phonetic Alphabet it is written /ˈsisu/. The usual first guess is 'see-SOO' or 'sis-ew', and both are wrong — the first syllable carries the emphasis.
Where the word comes from
Sisu derives from sisus, the Finnish word for interior, entrails, guts. That is the word's history, not its definition. 'Sisu means guts' is true as etymology; 'sisu means having guts' is a separate, courage-flavoured claim.

Say It Like a Finn
Stress the first syllable, keep it short, and this word stops being exotic and becomes simply useful — a two-syllable name for quiet courage.
