# Glossaries list - no separating lines

I am trying to produce a list of acronyms and definitions in which each entry is at some distance from the previous one. Distance of two lines worked out of the box and I am happy with it, but it is not applied to all entries - some entries start on the next line after the previous one ends. I am also seeing a lot of underfull hbox warnings, and I think it might have something to do with the space between entries, but I am not sure how to fix the problem. Is there a way to maintain that two lines space between entries even though the spacing between the words somewhat violates the allowed values?

Welcome to TeX.sx! Can you give a minimal working example (MWE), something that we can copy and paste and test?Also, there is no need to say thank you in your post. This might seem strange at first but as you continue to participate in this site, you will get used to it. It is not a sign of lack of politeness, but rather part of our trying to keep everything very concise. Accepting and upvoting answers is the preferred way here to say "thank you" to users who helped you. –  hpesoj626 Mar 20 '13 at 11:14
Without a MWE it's difficult to answer, but (assuming you're using the glossaries package) I suspect the package option nogroupskip may be what you're after regarding the spacing between lines. The underfull hbox warnings are probably caused by trying to fully justify text in a narrow column, which can happen depending on the glossary style. –  Nicola Talbot Mar 20 '13 at 13:21
Added a MWE. The nogroupskip made the look of the list consistent, but actually does the opposite of what I want - I do want vertical space between the entries. In the MWE is is not consistent - between some entries there is space, between others there isn't. –  Bini Mar 21 '13 at 9:40

You can modify the long style, which uses a longtable. Put this definition in your preamble:
\newglossarystyle{mylong}{

and use it with \glossarystyle{mylong} instead of \glossarystyle{long}. The above definition of \glossaryentryfield is exactly the same as the original of the long style, except that the 10pt space is added after each entry.
