Palaeographical terms
These descriptions provided here are rather basic and unsophisticated ones.

duct: the stroke of the pen
bole: a rounded part of a character, as in a or b or d
ascender: the upward stroke of a character as in b, l, h
descender: the downward stroke of a character, as in p, but note that such a stroke in y or g might be designated the tail
character: basically a letter
minim: the vertical strokes in m (3 minims), n and u (2 minims) and i (one minim)
suspension: a general contraction at the end of a word
superscript: a character written above the horizontal line of the other characters in a word
final: the position at the end of a word
medial: the position in the middle of a word

The hands in this charter
The general points to notice are that: (a) there are comparatively more contractions and suspensions than in earlier charters; and (b) that the hand has become generally more looped and rounded. The looping and rounding of the characters is perhaps best illustrated by the looped ascender of d, as in Dedi in line 1, but note that, although the ascender of lower case d is looped, the form of upper case D in Dedi and elsewhere, retains a fairly upright duct redolent of the 12th-century form.

The hand has also become more flourished, particularly in the form of split- or hooked-tops on the ascenders of characters such as l, b, k, and J, for example.

Note too that some characters have several forms within the same document. Here there are two forms of r: a longish r in general, but also an arabic 2-r, both illustrated in the same word roboraui:

Both forms of r existed in the twelfth century, but the form has become more rounded.
The form of a is another example, for, whilst the form is predominantly a single bole a, another form with an exaggerated ascender (a sort of two-compartment a) also appears. This exaggerated upper part of the a will later form another, upper bole. The following image illustrates both forms:

The long s which appears is not novel, for the long s appears in twelfth-century charters; the form of long s retains something of its character in the 12th century, for it is largely 'above the line' of the other characters, that is, it has a sort of ascender. Note, however, the form of upper case S, which is entirely different.
One final point to note is the residual whipping on the final long s in p[re]sentes which remains from the late-12th-century practice of whipping and decoration on ascenders on the first line of the charter.

Upper case characters
C as in Cl[er]ico:
D as in Dedi:
E in Excepta:
G as in G[er]suma[m]
H as in H[abe]nd[um]:
N as in Nichol[ai]:
P as in Priore:
R as in Regin[aldo]:
T as in Tenend[um]:
W as in Will[elmo]:
Interchangeable characters
The following characters are interchangeable:
u/v (both initially and medially); thus one might encounter vnus for unus or uel for vel;
t/c; thus one might encounter both servitium and servicium in the same document.

Contractions and suspensions
There is a relative proliferation of contractions and suspensions in this charter, which will become even more pronounced by c.1300. The looping and rounding of the hand is represented through some of these contractions and in the general suspensions. In the twelfth-century, suspensions, and many of the generic contractions, were either flatter or angular, but they have in this charter become more flourished, as the general suspension at the end of words or the contraction for medial -er- or the contraction for pre-.

medial -er- contraction: G[er]suma[m]

pro contraction

pre- contraction in p[re]sentes

per-/par- contraction in p[ar]ochia and note also the exaggerated upper bole in the final a

final -bus contraction in Successorib[us]

final -que contraction, here in cuic[un]q[ue] or cuic[um]q[ue]

flourish for a suspension at the end of a word (Test[ibus] in this particular instance, but the ending will depend on the context and case)

general contraction; although it most usually signifies the omission of minims, the horizontal stroke above a word can also represent a general contraction; here, of course, it represents the three omitted minims of the final m of annuati[m]; but below next

the same horizontal stroke represents a general contraction (B[eat]e)

superscription: a superscript character often means that the previous character (often u after q or an r) has been omitted; the example here is q[u]iete

final -et is often represented by this grapheme which resembles a z with a tail (for example, here as in scil[ic][et])

a horizontal stroke through b can represent medial -ber- as here in lib[er]e

this initial contraction represents con- as in [con]firmaui; it resembles a small 9 on the horizontal line with all the other characters

whether medially or finally, this contraction, which is a superscript arabic 2-r, represents -ur- or -ur, the latter in the passive form of verbs, but here in Fut[ur]i

used finally, this contraction, which resembles a 9 above the horizontal line of the other characters, represents -us, most usually in the form of verbs (e.g. dedim[us]), but here on the adjective san[us]

This section will be completed in due course.
