    You might have a worn synchro ring (no doubt this is a fairly high mileage car?). It's possible you could have a worn clutch or leaking clutch slave cylinder, so check the slave cyl. fluid level and check the slave for external leaks. You can test your clutch by trying to climb a grade in high gear--if the clutch is worn it should slip under those conditions. Also you can test your clutch pedal for "free play"--there should be some slack in the pedal when you press with your fingers, but if there is none at all, or way too much, the clutch may be ready for replacement.

    You might also try double-clutching to see if the grind goes away. That would suggest a synchro issue if it does go away.
