Eulingu is a corresponding language which means that we like to see both consistency and reflection in its structure for "easy remembrance" and "ease of use".
As you can see, the original forms of "estu", "esta", "esto" and "esti" had an "s" ending in order to correspond with the possessive "su/si/sa/so" but it was dropped for 2 reasons:
1) Clarity: The endings "a" and "o" are well known in Europe to reflect feminine or masculine terms, so no need to add "s", which can also be confused with plural forms (e.g. in Spanish).
2) Ambiguity: With the introduction of the quality-adjective-adverb ending "s" (as in -us/-is/-as/-os) it was necessary to remove "s" from the "tense forms".
