### [2nd conversion] 2nd conversion; switch 1st/2nd places

Source: embed:http://www.lojban.org/publications/draft-textbook/lesson07 Conversion *** In exercise 2-1, Part 4, where we had you devising keyword equivalents for the non-x1 places of each brivla, we had in mind the specific purpose of preparing you for Lojban 'conversion'. Not conversion to Lojban (we hope that you are already prepared for that), but conversion within Lojban. The term 'conversion' in this case derives from 'converse', a term which denotes that two things are being interchanged to form a kind of 'opposite'. In the case of Lojban conversion, the two things being interchanged are places in the place structure of a bridi. Specifically, in any bridi, conversion will result in the interchange of one of the other sumti places with the x1 place. Conversion is indicated by the cmavo of selma'o SE, namely "se", "te", "ve", and "xe". These respectively refer to 2nd, 3rd, 4th, and 5th conversion, and conveniently are built from consecutive Lojban consonants to make them easy to remember. You will use them a lot. 2nd conversion with "se" is the interchange of the x1 and x2 sumti places. 3rd conversion with "te" is, of course, the interchange of the x1 and x3 places. 4th conversion with "ve" interchanges the x1 and x4 places, and 5th conversion with "xe" interchanges the x1 and x5 places. The SE cmavo is placed immediately before a brivla. It causes any places of that brivla to be appropriately interchanged. The resulting place structure is renumbered, so you have a new x1 sumti after conversion. Why do you convert brivla? To allow you to put a different sumti in the x1 position and thus to say it first. This emphasizes that sumti over the other ones and specifically over the old x1 sumti that would otherwise have gone first; since you have presumably converted the brivla for a reason, the juxtaposition provides extra emphasis on the new x1 sumti. Let us take our well-worn example based on klama: mi cu klama la bastn. la .atlentas. ti la ford. by bluMyst
