A Tense Logical Sketch of German
As Bennett and Partee (1972) propose, adverbs such as gestern
'yesterday' or morgen 'tomorrow' may function-to located time within a
(1) for f a frame adverbial
- 56 -
'[ f JA 'stands for the semantic value of f in A (in the s,e,r s,e,r case of gestern only s is relevant). Notice that the time designated by f modifies reference time for the evaluation of the remainder of the sentence. This aspect of the analysis of frame adverbials, viz. that they specify an interval within which reference time must fall, is consistent with Bennett and Partee's (1972) term 'frame adverbial,' and it is consistent within the preformal intuition of reference time as "the time from whose vantage point the event is viewed." This was, of course. Reichenbach's position on such adverbials. which figured in his famous analysis of the English Present Perfect (Reichenbach, 1947: 294f) .
