J is in fact a much more recent invention than many of us would suppose[0]. It is worth adding, however, that it would not have saved G, except in English; our pronunciation of J, while close to the French and a couple others (with an added &#x2F;d&#x2F; at the front), is quite unique among languages that were written in the Roman alphabet at the time.<p>In any case, English suffers quite a few more more overloaded consonants that C and G. Most occurrences of &#x2F;z&#x2F; (a frequent sound in English) are marked with an S (<i>codes</i>), and a great many &#x2F;t&#x2F; sounds are written D (<i>typed</i>).<p>[0] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;J#History" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;J#History</a>
