question:
The B strings tuned w/ low E 7th fret harmonic-(6th string,7th fret).
answer:
The shorthand w/ is used to mean with. 2 pieces toast w/ gravy Is a shorter way of writing 'Two pieces of toast with gravy.' The B strings tuned w/ low E 7th fret harmonic-(6th string,7th fret). means 'The B strings tuned with low E, 7th fret harmonic . . .' Edited to add: As Denis de Bernardy correctly notes in the comment below, w/o means the opposite: without.

question:
I have recently heard in a Tv show that some guy said: He is stable-ish for now! What does this term mean exactly? couldn't find anything, what's the occasion to use? can we use the -ish suffix for any adjective?.
answer:
-ish 1) A suffix that makes any word or phrase more vague. 2) It can be used with any word and it's applied at the end to make the word into meaning 'kind of'. For eg. me = 'how are you feeling today?' you = 'i am feeling okay-ish' More 3) A suffix used to guesstimate a number or time. When referring to time '-ish' means within plus or minus 15 minutes. When referring to a number '-ish' means within 5. For eg. Guy1: What time is the party? Guy2: 7:30-ish Other definition: 4) suffix. used to describe an approximation, or likeness of the subject. (can be used alone as an adjective) So, here the meaning of the stable-ish to he is okay-okay or not good not bad.. Update reference by the request of @trevorD The term = ish

question:
Possible Duplicate: 'Did it close' vs 'Has it closed'? As a English non-native speaker it is difficult for me to understand when I must use present perfect or past simple because in my official language there isn't the present perfect tense. I know that present perfect is related to something that happened in the past but its result is important now. But for instance: The message has been sent. The message was sent. Please help me point me out any examples/contexts where I should use 1. instead of 2.
answer:
1 means that the action happened just now. You would typically see it in your e-mail program just after you send an e-mail. Your program might give you this message to let you know that the message you just sent has indeed been sent. 2 refers to something that happened at some time in the past. It could have been an hour ago, a day ago, or even a century ago! But it wasn't just now.
