They moved to Rhydlewis, just to the west of Llandysul, where he spent what appears to have been a poor (his mother was expelled from chapel for not paying her dues) and unhappy childhood, falling foul of the Cymrophobic education system of the time.

2004, Jim Perrin, Travels with the Flea... and Other Eccentric Journeys, →ISBN:

Formerly Mr Driscoll held court at that bastion of Welsh nationalism, The Cayo Arms, on Cardiff’s Cathedral Road, where he could be consulted on any matter concerning Cymro-Irish relations as long as an element of rugby football was included in the conversation.

1862, Britannicus (pseudonym), “Vindication of the mosaic ethnology of Europe”, in The Cambrian Journal, page 149:

And as for the physical type or types, the light complexion is very unlike that of the earlier British or Iberian race, though we cannot say that the ruling Cymro-Gaelic stocks were not fair.

1907, John Beddoe, Joseph Hamberly Rowe, “The Ethnology of West Yorkshire”, in The Yorkshire Archæological Journal, volume 19, page 32:

Some people derive Berwick from the Cymro-Teutonic compound Aber-wick. This sounds most reasonable, Aber signifying the mouth of a river, while some of the Saxons whom Ida gathered into one kingdom certainly then or later had a "wick" or town here. The Celts would naturally have emphasized the penultimate and made it Aberwick [...]

History proves that for centuries the Anglo-Saxons fought, formed treaties, intermarried with the Cymbric race [...] They even themselves passed through intermixture out of the properly Anglo-Saxon into the Cambro-Saxon phase, constituting in fact a new race.

1868, Thomas Nicholas, The Pedigree of the English People, page 442:

In present-day Colloquial Welsh borrowed nouns retain noun plurals in the exact shape that they occur in Cambro-English; for example (in north-western areas): [kondəktərs] 'conductors', loris 'lorries'.

/ˈlɒd͡ʒɪkəʊ/

Yet what is to be the status of a law of optimality to the effect that “whatever possibility is for the best is ipso facto the possibility that is actualized.” It is certainly not a logico-conceptually necessary truth; from the angle of theoretical logic it has to be seen as a contingent fact — albeit one not about nature as such, but rather one about the manifold of real possibility that underlies it. Insofar as it is necessary at all it obtains as a matter of ontological rather than logico-conceptual necessity, while the realm of possibility as a whole is presumably constituted by considerations of logico-metaphysical necessity alone.¹⁴
¹⁴ The operative perspective envisions a threefold order of necessity/possibility: the logico-conceptual, the ontological or proto-physical, and the physical.

Romano-

The ties between Tudor Vladimirescu and the liberation movement in Serbia also deserve to be mentioned, and especially the fact that the Adunarea norodului (the People’s Assembly) seemed to be of Serbian inspiration. Thus Romano-Serbian relations were tied in a new and institutional aspect, which unfortunately had no consequences.

At the beginning of the 19th Century there were seven autocephalous or autonomous churches in the Balkans: Four of the Serbian language (Montenegro, the Patriarchate of Carlovitz, the Archbishopric of Belgrade and the autonomous Church of Bosnia-Herzegovina), two Romanian speaking (Romania and Transylvania), and one Romano-Serbian (Rucovina).

Blondel needn’t have been so concerned about Tisza’s negotiations as Hungarians hostile to Romanian demands were themselves sabotaging any efforts to offer concessions. Certainly the reporting in the Pesti Hirlap of the text of a Romano-Serbian treaty, supposedly signed on 24th June 1913, described as aiming at dismemberment of the Austro-Hungarian Empire, was recognised by the official papers of Vienna and Budapest as an attempt to put an obstacle in the way of the talks.

quetta-

Blend of q (an arbitrarily chosen initial letter) + Latin decem (“ten”) + -ta (to match the final syllable of most SI prefixes from peta- upwards).
Coined by Richard J. C. Brown and adopted by the General Conference on Weights and Measures in 2022 as an expansion to the metric prefixes beyond 10^(±24).
Some popular unofficial terms already in use were hella-, bronto- and xenna-, but terms beginning with the same letters as existing prefixes were considered undesirable, as were as those beginning with common scientific letters such as b or x. Richard J. C. Brown suggested that the new terms begin with r and q, due to their rarity as unit symbols, and that the trends followed by the other prefixes be continued: that they be based on Latin or Greek; that large prefixes end with -a and small prefixes end with -o; that they should be in corresponding large and small pairs; and that the first letters of each prefix should be in reverse alphabetical order (as has been the case for the newer prefixes). He therefore suggested ronna- and ronto- (evoking Ancient Greek ἐννέα (ennéa) and Latin novem (“nine”)), and quecca- and quecto- (evoking Ancient Greek δέκα (déka) and Latin decem (“ten”)), because as 10²⁷ and 10³⁰ when written have nine and ten groups of zeroes, respectively. These were adopted, with quecca- changed to quetta-.
