Pronounce it as /ˌθrəˈaʊt/ (US/UK) with three phonemes at the start: /θ/ (thin sound), /r/ (rhotic approximant, though some accents may be less rhotic), and /ə/ or a schwa in the first unstressed syllable. The primary stress lands on the second syllable: 'aʊt' rhymes with 'out.' Your mouth starts with a voiceless interdental fricative, moves to an R-controlled vowel in the second syllable, and ends with the diphthong /aʊ/ in 'out'.
Common errors include dropping the initial /θ/ sound (saying 'throughout' as 'roout') and misplacing the accent, producing something like 'thru-out' with equal stress. Another pitfall is muting the /r/ in non-rhotic accents, which can alter the word's rhythm. Correct by practicing the /θ/ at the start with a light air flow, keeping the /r/ prominent in 'rə' and ensuring the /aʊ/ is a clear diphthong rather than a simple /a/ followed by /t/.
In US accents, you’ll hear a rhotic /r/ and a clear /ə/ plus a strong /aʊ/ in 'out.' In many UK varieties, the /r/ may be less pronounced or non-rhotic in some contexts, with a slightly shorter 'ə' and a more clipped rhythm. Australian pronunciation usually keeps a credible /r/ in connected speech but with a smoother, less retroflex /ɹ/ and a slightly more centralized /ə/ before /aʊ/. The diphthong remains /aʊ/ across dialects, but vowel quality and stress can shift subtly due to rhythm and intonation.
The difficulty lies in starting with the voiceless interdental /θ/ and the rapid transition to the rhotic or non-rhotic /r/, followed by a strong diphthong /aʊ/. The sequence requires precise timing of vowel rise and contraction across syllables, without adding extra vowels between 'th' and 'rough' sounds. Practicing the initial /θr/ cluster and the /ə/ before /aʊ/ helps achieve a natural, fluent rhythm.
A unique feature is the secondary stress pattern and the way the /ə/ is reduced in the first syllable while the second syllable carries the main stress. You’ll want to avoid an elongated /ə/ and ensure the /aʊ/ in 'out' is the strongest vowel. Also pay attention to keeping air-flow steady through the 'th' to avoid a lisp or a lag in voicing.

Throughout originates from the compound of 'through' + 'out.' 'Through' traces to Old English þurh, from Proto-Germanic thurkh, conveying motion across the interior of something. 'Out' comes from Old English ut, from Proto-Germanic *ut, indicating outward direction. The combined form began to appear in Middle English to emphasize distribution or presence across a span, not just at the edges. Early uses describe movement or visibility from start to finish, or across an entire area, with senses of completeness, entirety, or ubiquity. Over time, throughout became a fixed adverbial and prepositional phrase, frequently paired with time spans (throughout the year) or spaces (throughout the city) to denote pervasive coverage. The word’s strength lies in its ability to bound a scope with completeness, contrasting with narrower terms like 'during' or 'in' which imply partial coverage. First known attestations appear in 14th–15th century English texts, evolving from literal spatial readings to broader figurative uses in literature and common speech as a marker of comprehensive extent.
