Welsh to Mongolian: distinguish not reading from not having read
Welsh aspect words need a complete target interpretation
The official Welsh Foundation guide distinguishes bod followed by yn and a verb noun from constructions with wedi. These patterns help separate an activity from a completed event. A Welsh negative report should therefore be read for its temporal relationship before a Mongolian negative verb is selected.
Tokyo University of Foreign Studies explains that Mongolian aspectual negatives interact with past versus nonpast time. Several affirmative constructions correspond to the same negative pattern. Its уншаагүй байна can, in the appropriate context, concern not reading now or not having read yet. A target expression is consequently not necessarily defective because it lacks a separate visible counterpart of Welsh wedi.
For an original Welsh reading update, compare someone who is not reading the document during a meeting with someone who has not yet read it before the meeting. The first concerns an activity at a particular time; the second concerns whether the relevant reading has occurred. Translating both as an established refusal to read would add a different claim.
A past reference point is different from a present delay
The Mongolian lesson illustrates уншаагүй байсан with interpretations anchored to a past situation, including not reading then and not having read by then. Its auxiliary matters alongside the negative verbal form.
A Welsh account can describe what was still unfinished when a colleague arrived, even though the task has since been completed. The Mongolian result should not relocate that unfinished state to the present. Conversely, a current report that reading remains outstanding should not become merely a historical observation. Keep a source phrase identifying the relevant meeting or arrival attached to the state it actually locates.
Welsh bod constructions make this especially relevant because tense information can stand in the auxiliary while the lexical verb remains a verb noun. Matching only that lexical item to a Mongolian reading-related root would overlook the distinction. The source auxiliary, aspect construction, and temporal phrase work together; none can be reconstructed reliably from the main vocabulary alone.
A repeated habit is another claim again
The same Mongolian lesson distinguishes уншдаггүй байсан for a past habitual absence of reading. This is not automatically interchangeable with a statement that one particular document remained unread at one particular moment.
In an original Welsh account of a former routine, someone may describe a period when they did not read reports regularly. A separate sentence may identify one report they had not read before an interview. The first characterizes a recurring pattern; the second describes the status of an individual event relative to a deadline. A Mongolian translation should retain that difference rather than make one missed report evidence of a general habit.
The practical question is therefore more precise than whether a negative marker appears. Determine whether Welsh denies a current activity, an event completed by a reference point, or a former recurring practice. The appropriate Mongolian construction must preserve that particular denial, including its time frame.
