I'm seriously considering an overhaul of my naturalistic conlang, an isolate set in Finland/Russia, to include grammatical tone. I'd like to get your input on this idea, because I'm concerned about how to implement it most realistically.
1) No matter the case, nouns of one syllable maintain a low tone on the sole vowel or syllabic consonant in the singular and acquire a high tone there in the plural. Nouns of two or more syllables maintain a low tone on the first vowel or syllabic consonant in the singular and acquire a high tone there in the plural.
2) To form the genetive, singular nouns of one syllable acquire a falling tone on the sole vowel or syllabic consonant. Plural nouns of one syllable, undergoing reduplication and consonantal dissimilation, maintain a high tone on the now-first vowel or syllabic consonant and acquire a falling tone on the now-second vowel or syllabic consonant. Singular nouns of two or more syllables maintain a low tone on the first vowel or syllabic consonant and acquire a falling tone on the final vowel or syllabic consonant. Plural nouns of more than one syllable maintain a high tone on the first vowel or syllabic consonant and acquire a falling tone on the final vowel or syllabic consonant.
3) The simple past tense is formed with a low-toned -V suffix, sometimes along with ablaut and consonantal shift in the verb root: e.g., jodolosi "he worked" (from dolos "to work"). The past tense with progressive aspect is formed with a high-toned -V suffix: e.g., jodolosí "he was working". The past tense with habitual aspect is formed with a CV- prefix in addition to the low-toned -V suffix: e.g., jotodolosi "he used to work/he would work".
The past tense with perfect aspect is formed with a falling tone on the first vowel or syllabic consonant of the verb root in addition to the low-toned -V suffix: e.g., jodòlosi "he has worked". The past tense with perfect and habitual aspects is formed with the CV- prefix and a falling tone on the first vowel or syllabic consonant of the verb root in addition to the low-toned -V suffix: e.g., jotodòlosi "he has been working".
The past tense with pluperfect aspect is formed with a high tone on the first vowel or syllabic consonant of the verb root in addition to a falling-toned -V suffix: e.g., jodólosì "he had worked". The simple past tense with pluperfect and habitual aspects is formed with the CV- prefix and a high tone on the first vowel or syllabic consonant of the verb root in addition to a falling-toned -V suffix: e.g., jotodólosì "he had been working".
4) The present tense with progressive aspect is formed by leaving the verb in its basic form: e.g., jodolos "he is working". The present tense with habitual aspect is formed with the CV-prefix: jotodolos "he works".
5) The simple future tense is formed with a low-toned -CV suffix: e.g., jodolossa "he will work". The simple future tense with progressive aspect is formed with a high-toned -CV suffix: e.g., jodolossá "he will be working". The future tense with habitual aspect is formed with the CV- prefix in addition to the low-toned -CV suffix: e.g., jotodolossa "he will work/he will be working".
The future tense with perfect aspect is formed with a falling tone on the first vowel or syllabic consonant of the verb root in addition to the low-toned -CV suffix: e.g., jodòlossa "he will have worked". The future tense with perfect and habitual aspects is formed with the CV- prefix and a falling tone on the first vowel or syllabic consonant of the verb root in addition to the low-toned -CV suffix: e.g., jotodòlossa "he will have been working".
6) I am interested in the possibility of a dependent clause being formed with a high tone on the subject-concordance prefixes: e.g., jódolos "who is working/that he is working". My goal is not to complicate the grammar of this conlang as much as possible, though.
Thanks for your feedback.
