# たい
## Japanese
### Etymology 1

* Alternative spelling
* 度い (obsolete)
From たし (-tashi), generally regarded as a shift from Old Japanese いたし (itasi, “painful”), modern 痛い (itai). Appears as a verbal suffix from at least The Tale of the Heike completed before 1330. Replaces previous volitional or desiderative suffix まほし (mahoshi).

#### Pronunciation

* IPA: [ta̠i]
* In Tokyo speech, the accent of the verb construction depends on the suffixed verb:
** If the suffixed verb is accented, the accent falls on the first mora in the suffix: つく​る [tsùkúꜜrù] (Nakadaka) → つくりた​い [tsùkúrítáꜜì] (Nakadaka)
** If the suffixed verb is non-accented and the suffix is in the dictionary form (nonpast), the result is either non-accented or accented on the first mora of the suffix: あそぶ [àsóbú] (Heiban – [0]) → あそびたい [àsóbítáí] (Heiban – [0]) or あそびた​い [àsóbítáꜜì] (Nakadaka). Further conjugation is based on the accented version.

#### Suffix

たい • (-tai) -i (adverbial たく (-taku))
* Used to form the desiderative of verbs: want (to do); hope (to do)
    読(よ)みたいなら貸(か)すよ
       yomitai nara kasu yo
       If you want to read it, I can lend it to you.
    彼(かれ)は注(ちゅう)目(もく)されたい

    アイスが食(た)べたい
       aisu ga tabetai

* (only with verb ある, である and honorifics) Expressing a wish of the speaker: I hope that; I wish that

##### Usage notes

* Outside of questions, the suffix たい (-tai) is used mainly to talk about the speaker's own wants. When describing the wants of someone else, the suffix たがる (-tagaru) is used instead.
* Attaches to the 連用形 (ren'yōkei, “continuative or stem form”) of verbs. The result is conjugated like an adjective (形容詞) but allows for the combination with nominal particles such as を, unlike regular adjectives. Both particle uses have been widespread since the Muromachi period.

          kanojo wa kaeritai
          She wants to go home.
       彼(かの)女(じょ)は帰(かえ)ってほしい

* Verb with たい can sometimes mark the grammatical object with が, besides the normal object marker を.
       アイスが食(た)べたい
          aisu ga tabetai
          I want to eat ice cream.
       アイスを食(た)べたい
          aisu o tabetai
          I want to eat ice cream.
* This word is morphologically an inflectional suffix. It is classified as 助動詞 (jodōshi, “auxiliary verb”) in traditional Japanese grammar.
