Yr Allt (SN 552 024)
There has been a Significant Name Change to a hill that is listed in the 30-99m Twmpau, with the summit height, bwlch height and their locations, the drop and status of the hill derived from LIDAR analysis conducted by Myrddyn Phillips.

The criteria for the list that this name change
applies to are:
30-99m Twmpau - Welsh hills at or above 30m and below 100m in height that have 30m
minimum drop, with an accompanying sub list entitled the 30-99m Sub-Twmpau,
with the criteria for this sub category being all Welsh hills at or above 30m
and below 100m in height with 20m or more and below 30m of drop, with the word
Twmpau being an acronym standing for thirty
welsh metre prominences and upward.

The hill is adjoined to the Mynydd Sylen group of
hills, which are situated in the southern
part of South Wales (Region B, Sub-Region B5), and it is positioned with minor roads to its north and west,
and the A4138 road to its south, and has the town of Llanelli towards the west
south-west.
When the original 30-99m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website, this hill was not
included in the Hills to be surveyed
sub list, as it was considered not to meet the criteria then used for this sub
category.
After the sub list was standardised, and
interpolated heights and drop values also included the details for this hill
were re-evaluated and it was listed under the point (Pt. 97m) notation with 26m
of drop, based on the 97m summit spot height and the 71m bwlch spot height that
appeared on the Ordnance Survey Vector Map Local hosted on the Geograph website
and which was entitled the Interactive Coverage Map.

As the summit of this hill comprises bounded land
the details for it were examined on the Tithe map. The
term Tithe map is generally given to a map of a Welsh or English parish or
township and which was prepared after the 1836 Tithe Commutation Act. This act allowed tithes to be paid in cash
rather than goods. The Tithe maps gave
names of owners and occupiers of land in each parish and importantly for
place-name research they also included the name of enclosed land. This enclosed land is usually based on a
field system, however not every field is given a name, but many are and
especially so in Wales.

The enclosed land where the summit of this hill is
situated is given the number 230 on the Tithe map, this can be cross referenced
against the apportionments; it is these apportionments that give the name of
the owner or occupier of the land as well as the name of the land. The land where the summit of this hill is
situated is named as Purchase on the Allt
in the apportionments, with the details on the Tithe map appearing in the parish of Llangennech and in the county
named as Carmarthen.

The intricacies of language and prioritising one
in favour of another for listing a hill is fraught with complication, with
originating Cymraeg names being anglicised and also originating English names
being cymricised, examples such as these are more common in border country and
especially so for anglicised forms.
There is no steadfast rule that fits all, but as a standard a name that
has its origins in the Welsh language and where this is substantiated by either
historic documentation and/or contemporary usage should be prioritised in
favour of a contemporary anglicised or English version of the name. Likewise, if a name exists where an element
of it is in English and if this name applies to a hill that is situated in a
Welsh speaking part of Wales it is standard practice to use a full Welsh term
for the name. It is also standard
practice to use a Welsh name for a hill if another name exists that has
originated in a different language.
Therefore, the name this hill is now listed by in
the 30-99m Twmpau is Yr Allt, and
this was derived from the Tithe map, with the prioritised naming protocol for
language being used.
