These two answers cross each other in the grid so the middle letter for both answers must be the same! I thought of "Cater" for feed and "Augur" for predicting the future but the middle letters ('t' and 'g') are not the same so at least one answer is wrong. These two answers don't cross with any other words in the grid.
Also:
26a Spiritual part of askance (2) ?0
27d Central idea (4) CL?U
Any suggustions for any of these gratefully recieved.
