Casiy

Note: This language has been abandoned, feel free to do whatever you please.

Casiy, pronounced xä-siːʈ̺ isn't a language in the sense of being spoken by a culture or by many people but rather just a conlang I made up for me to better communicate with myself and to be more secretive, feel free to use it if you want. It is also based off to an extant on Hebrew and Arabic (that's what I think at least), while it's actual stuff is different from English much of it's structure is similar to English.

General Information
Casiy has many retroflex consonants and is unique. It can be difficult for a non-linguist to understand and pronounce or even decipher so that's what made Casiy such a great cant language.

Consonants

 * /ɹ/ and /ɻ/ are very rare and are usually instead substituted with their counterparts /ɾ/ and /r/
 * All fricatives are pronounced as a /x/ sound if they follow an open, open-mid, or near open vowel such as for an example if /f/ was followed by an a it would become /xa/ instead of /fa/, unless if they are /ɸ/, aspirated, breathy, or followed by a mid vowel
 * If /ɭ/ is followed by an open to open-mid, near open, or rarely mid vowel it will become apical, either subapical or apical with the tongue more drawn back if an open vowel follows it. if followed by an open-mid vowel. If /ɭ/ is followed by a closed, closed-mid, near back, and almost always mid vowel it will become laminal. If it is preceded by a vowel instead then it will be subject to the rules of most retroflexes instead.
 * /l/ is only used if followed by /a/ or /e/, if it is not then it will become silent
 * If any other retroflex including /ʈ/, /ɖ/, or under certain circumstances /ɭ/ is followed or preceded by a front vowel it will become apical, mid it becomes subapical, back it becomes laminal
 * /d/ and /t/ are complicated. If /d/ or /t/ has a vowel come before them then they will become a retroflex, if they have a vowel coming after them they will become dental, if they have both or no vowel coming after and before them then they remain normal
 * Only retroflex, lateral fricative, fricative, and labio-dental consonants may be geminated
 * All consonants except for trills, approximants and /l/ can be nasalized

Vowels

 * /i/ is usually pronounced with more stress and with the very back of the tongue touching the roof of the mouth with the rest of the tongue hovering just below it.
 * /ʏ/ is less rounded than usual
 * /ɶ/ is pronounced with the tongue much further back than usual
 * /a/ is always aspirated and breathy, if it isn't then it become /ä/
 * It is illegal to have /i/ and /u/ a consonant away or less from each other if a trill or approximant came before them
 * Only /ø/, /ä/, /ə/, /u/, /o/, /a/, and /i/ can be geminated. /æ/, however can be geminated slightly if /ɱ/, /ʙ/, /r/, or /ɳ/
 * If /e/ or /ø/ is geminated then they will become higher in pitch but if followed by an alveolar then they will become lower in pitch
 * If /e/ or /ə/ are nasalized they cannot be geminated and must become higher in pitch and slightly more rounded

Digraphs

 * Only bilabial affricates and fricatives can be used before /e/ and /ʌ/
 * /t͡s/ and /d͡z/ gain more stress 1 consonant away or at the end of a word
 * If /t͡s/ or /d͡z/ precede a front vowel then they will become less stressed

Diphthongs

 * Front diphthongs are longer and less stressed while Back diphthongs are shorter and more stressed
 * More close diphthongs have more stress on the last vowel while more open diphthongs have more stress on the first vowel
 * If /ä͡u/ is used after a bilabial it will become /a͡ù/
 * It is illegal for two diphthongs to be used if they are not at least 2 consonants or 1 vowel apart
 * If a digraph comes before a diphthong then that diphthong will be degeminated and slightly more rounded, if a digraph comes after a diphthong that diphthong will become geminated and slightly less rounded, if it is unrounded it will become higher in pitch

Phonotactics
Casiy's syllable structure is rather simple; (C(1 - 2))CV(2)(V)(C)(C). There has to be at least one vowel and consonant before a vowel or else it is considered just a letter and not a word. There can be an optional vowel after the nucleus but if the nucleus is a diphthongs or vowel cluster then the vowel after the nucleus would be made illegal, something similar applies to the first optional consonant, it can be a consonant cluster or diagraph but if the nucleus is a diphthong or vowel cluster it would have to be reduced to a single consonant or less.

Writing
Since Casiy was made by me, a Latin writing system user and it's a cant language it's writing system is in Latin script.
