forming wh-question phrases. It can be combined with a demonstrative, the dubitative, the rhetorical interrogative, and the emphatic assertion: sáwé (< sá + áwé), sáyá, ... — focused question, "... is that?" sgé (< sá + gé) — dubitative question, "maybe?", "perhaps?" ságwshéi — "I wonder?" sdágáa (< sá + dágáa) — "(what) on earth?", "really?" Phrasal particles Phrasal particles may occur after focus particles that occur with or without demonstrative finals. The following are postphrasal particles, thus they may only occur after the phrase that they modify. tsá — "only then" tsú — "also" s'é — "first", "really!" déi — "now", "this time" x'wán — "be sure to" tsé — "be sure not to" Except for x'wán and tsé, the above may occur after the focus particles. The following are prephrasal particles, i.e. they occur before the phrase that they modify. Naish and Story call these "pre-marginals". ch'a — "just", "the very" ch'as — "only", "just" ch'ú — "even" tlaxh — "very" Mobile particles These particles may occur before or after any phrase in a clause. tlei — "just," "simply," "just then" déi — "already," "by now" tsu — "again", "still", "some more" Compare the mobile particle tsu with the postphrasal particle tsú. Both the sentence káaxwei tsu eetéenaxh xhat yatee "I need more coffee" and the sentence káaxwei tsú eetéenaxh xhat yatee "I also need coffee" are acceptable. However the sentence *tsú káaxwei eetéenaxh xhat yatee is syntactically inadmissible because the particle tsú is postphrasal, i.e. it cannot precede the phrase it modifies, in this case the noun phrase káaxwei. The corresponding sentence with the tsu particle in front, tsu káaxwei eetéenaxh xhat yatee "I need coffee again/still" is in contrast syntactically acceptable. Thus a Tlingit listener will recognize the tsu particle in a phrase-initial position without confusion but tone is necessary to distinguish it in a phrase-final position. For this reason the tsu particle is often used prephrasally although it is syntactically admitted in either position. Thus the song name Tsu Héidei Shugaxhtootaan could also be héidei tsu shugaxhtootaan, but placing the tsu in front has the advantage of unambiguity, and thus seems more euphonious to native speakers. Note that déi is a homonym with the noun déi "path, way, road". [How are these differentiated in speech?] The particle tlei is easily confused with tléil "no, not", but as with the tsu/tsú pair the tone makes them
