I'm quite new to Latex and slowly writing/making my book (electrical measurements, some signal processing, that stuff), but sometimes I get trapped in probably trivial issues. My first writing is with Lyx (please, understand me, I've been using Word for 25 yrs!) and then ERT and preamble for fine tuning.

\paragraph is my last section heading and is of the run-in type; I want to keep words tight and avoid interword spacing sticking to a minimum.

I have seen that \tolerance and \wordsep are two low-level parameters that have to do with that.

Question: Is it possible to redefine \paragraph reducing \wordsep and words are more packed together?

Here is a small excerpt where "Resonance with a known capacitance (frequency domain, narrow-band)" is way too long.

\documentclass[10pt,english]{book}
\usepackage{charter}
\setcounter{secnumdepth}{3}
\setlength{\parskip}{1.5mm}
\setlength{\parindent}{0pt}

\begin{document}
\chapter{\label{chap:Ch1_Circuits}Circuits and Basic Relationships}

\subsubsection{Experimental determination}

\paragraph{Use of a RCL bridge}
This is the simplest and most straightforward method, provided that the RCL bridge with
adequate performance is available: bla bla bla bla bla bla bla bla bla bla bla bla 

\paragraph{Resonance with a known capacitance (frequency domain, narrow-band)}
This method works well for many inductors that have non-standard package
(e.g. home made inductors),  including circuits and cables, and when the frequency
range is extended, but not too much. bla bla bla bla bla bla bla bla

\end{document}

... and Happy Easter

    your question is massively unclear. You need to give an example, tex tries hard to "avoid too much interword spacing" so if you are getting too much it is very hard to say what to change unless you show why you are getting too much. – David Carlisle Apr 03 '15 at 22:15

    also the text of your question does not seem related to the title, which appears to be about kerning for the letter "a" ? – David Carlisle Apr 03 '15 at 22:16

  • ok, thanks, I work on this, and sorry for the broken title – andrea Apr 03 '15 at 22:22
  • No, it's not possible to shrink that title: there's no way “This” can find place on the previous line. By the way, there's no \wordsep parameter. – egreg Apr 03 '15 at 23:27
  • @egreg -Thank you. Now I am sure and will go for some "hand patching" of the most critical cases. [marginal comment: \wordsep is cited in other 3 threads and I understood it was a low-level parameter]. – andrea Apr 03 '15 at 23:36
  • I think that's a package-specific token: http://tex.stackexchange.com/a/126764/17423 – Sean Allred Apr 04 '15 at 00:09
  • @ Sean Allred -Right, read the link and got it, thanks! I can only improve :$ – andrea Apr 04 '15 at 00:17
  • The breaking in the example you supplied seems fine, the title is not very stretched even if the white space was shrunk to its minimum amount This would not fit (and if it did fit it would look worse with just one non-bold word on the line). If you were breaking this by hand how would you break the lines? what do you want TeX to do differently here? – David Carlisle Apr 04 '15 at 10:02
  • @David Carlisle -Yes, got the point better that I could explain (at 2am not all things are clear!). First, shrinking the \paragraph wouldn't produce nice results (I will patch reducing the length, removing some words, etc. .. no other way, and probably it will benefit). Second, the third example you give below is right what I was thinking, and I couldn't write it down, only playing around with syntax: the zero with \z@, @plus and @minus. Thanks! – andrea Apr 04 '15 at 12:44

By "bad interwrod spacing" are you are pointing to the space between "brigge" and "This"? In this case, you can redefine \paragraph to change this fixed space:
