Tinglish

Characteristics and examples (direct translation) include :

• omission of pronouns
• zero copula
• use of present tense + already, in contrast to past tense of Standard English
• non-standard use or omissions of articles, declension, prepositions, and conjugation.
• addition of Thai final particles, e.g., I don’t know na
• any and every are used interchangeably
• different use of conditional constructions
• pronunciation of silent letters in a word
• omission of the consonant at the end of words ending in a diphthong and a consonant, for instance Mickey Mouse pronounced “Mickey Mao”, white wine pronounced “why why”, and news pronounced “new”.
• inserting vowel sounds into consonant clusters, for instance slow pronounced “sah-low”
• no use of double negatives
• /ɹ/ pronounced as /l/ or rarely as /r/
• ⟨th⟩ pronounced as /t/
• using "N" to replace an "L" sound at the end of the word, for instance "school" pronounced "sah-koon" or "football" pronounced "futbon"
• moving "S" on singular verbs to the subject, for instance "He's talk too much" instead of "He talks too much"
• omission of prepositions, for instance "I wait you" instead of "I'll wait for you" or "I listen him" for "I listened to him".
• "very" and "very much" are used interchangeably, for instance "I very love my daughter" and "She beautiful very much".

As some sounds in English simply don't exist in the Thai language, this affects the way native Thai speakers pronounce English words :

• Non-rhotic, e.g., more -> maw ([mɔː]), gear -> gia ([kia]), and car -> kah ([kʰaː]).
• all syllables are stressed with the same intensity
• omits consonant clusters. "Mixed" is pronounced "mik".
• final consonants are often omitted or converted according to the rules of Thai pronunciation: l and r become n; p; b and f become an occlusive p; t, th, d, s, st, sh, ch and j become an occlusive t.
• Perversely, given the language constraints for d and l among the rules above, l can become r and d can become sh, for instance blood can become brush.
• If there is more than one consonant at the end of a syllable, only the first is pronounced, the others are omitted. "W" and "Y" sounds count as consonants, too. So, "count down" becomes "cow dow", "size" becomes "sigh"
• "sh" and "ch" sounds can be indistinguishable as the Thai language does not have the "sh" sound, e.g., ship/chip, sheep/cheap
• "v" sound is almost always replaced by "w" sound, e.g. "TV" is pronounced "tee-wee" and "video" is pronounced "wee-dee-oh".
• "g" and "z" sounds are usually devoiced, e.g., dog -> dock ([ˈdɔk]), zoo -> sue ([ˈsuː])
• "th" sound is often replaced by "t" or "d" sound. Particularly, the voiceless "th" (/θ/) is replaced by [t] or [tʰ], while the voiced "th" (/ð/) is replaced by [d], e.g. thin -> tin ([ˈtin]) or [ˈtʰin]), through -> true ([ˈtʰɹuː]), thank you -> tang kyou ([tɛŋ kiw]) or ([tʰɛŋ kiw]), and then -> den ([ˈden]).
• ambiguity between the short "e" (/ɛ/), as in "bled", and a long "a" (/eɪ/), as in "blade" because both are pronounced as [e(ː)].
• "e (vowel) " so cherry is pronounced chuhr-lee, error is pronounced err-rer

In Thai, certain consonants cannot occur as a consonant cluster. Such illicit clusters include those with sibilant sounds followed by obstruent sounds. In order to avoid such illicit forms, a short "a" (ah; [ə]) sound is added between these consonants:

• start - sahtat (/səˈtaːt/)
• sleep - sahleep (/səˈliːp/)
• speak - sahpeak (/səˈpiːk/)
• snore - sahnore (/səˈnɔː/)
• swim - sahwim (/səˈwim/)
• school - sahkoon (/səˈkʰuːn/)
• album - alabum (/ələˈbam/)

'R' or 'l' after another consonant may be omitted completely.
