Question Words
The basic question words of Lisadian can be summarized as na (yes-no, sentence-final question marker), lae (what), liva (which, which one), laru (when, what time), and laumis (who). All other question words are formed from these basic question words through the use of case markings. In the case of lae, the following question words are commonly used: lin (where), line (where to), lise (where from), lu (how), laen (rhetorical question, how come, why, how), dheli (why, for what reason), and dhela (what for, for what purpose). Lae can take the adjectival suffix iva to become liva which can then be inflected to agree with the noun it modifies to mean “which.” Laru comes from the contraction of la and hru (time) and has the following forms: larose (until what time) and larosi (from what time). Laumis comes from the contraction of la and gwemis (person) and can be inflected accordingly for number and all cases. The inflectional tables for la and launid are given below:

Demonstratives and Spatial Adverbials
There are four basic types of Lisadian demonstratives pronouns: involved personal, uninvolved personal, proximal, and distal. Each type of demonstrative then has three separate sub-types based on verticality relative to the speaker and direction of gravity: high, mid, and low. The personal demonstratives may also be understood as spacial variations of the 2nd and 3rd personal pronouns, but the involved high, low, and adjectival forms are rarely used except in the vocative case. Each demonstrative can take on the adjectival ending -iva to modify a noun. The following table shows all uninflected forms of demonstratives:
| High | Mid | Low | ||
| Uninvolved | nom. | viu (-l) | ve | veith |
| adj. | viliva | viva | vithiva | |
| eng. | "them up there" | "they" | "them down there" | |
| Involved | nom. | giu | gae | geith |
| adj. | giliva | giva | githiva | |
| eng. | "you up there" | "you" | "you down there" | |
| Proximal | nom. | niu (-l) | ne | neith |
| adj. | niliva | niva | nithiva | |
| eng. | "this up here" | "this" | "this down here" | |
| Distal | nom. | siu (-l) | se | seith |
| adj. | siliva | siva | sithiva | |
| eng. | "that up there" | "that" | "that down there" | |
Spatial adverbs are derived from the proximal and distal demonstratives using the inessive, illative and ablative cases.
| Inessive | Illative | Ablative | ||
| Proximal | High | nilin "up here" | niune "up hither" | niuse "from up here" |
| Mid | nein "here" | neine "hither" | neise "from here" |
|
| Low | nithin "down here" | nithine "down hither" | nithise "from down here" |
|
| Distal | High | silin "up there" | siune "up thither" | siuse "from up there" |
| Mid | sein "there" | seine "thither" | seise "from there" |
|
| Low | sithin "down there" | sithine "down thither" | sithise "from down there" |
