They are mīs and tīs; so far as I can tell, they are found exclusively in Old Latin inscriptions (i.e. you won’t encounter them in archaic imitations of Old Latin designed by Classical authors). The more you know…
If anyone has further thoughts or resources on these, feel free to share below.
The words enim, etenim and neque enim are all postpositive tools for emphasis. They typically occur in the second position, but may occur in the third, where the second word is emphatic.
Enim and its emphatic counterpart, etenim, may add an affirmative pulse to a statement or clause. In this sense, they function much as equidem, certē and vērō, though these are not necessarily postpositive.
…sed enim istaec captio est: …but this is clearly a trick!
in hīs est enim aliqua obscūritās: in fact, these matters contain some mystery.
Quid agis?—Nihil enim: What are you up to?—Nothing, truly! (~Nothing, I swear!)
Etenim is very popular in parenthetical phrases.
dux huius agminis Caesar est (etenim est prīmus mīlitum): the leader of this line is Caesar, because, of course, he is the first among soldiers.
Kate Medoppidum (quae etenim modo hērēdem peperit) nōn trēs diēs vīsaest: Kate Middleton, who as you know just gave birth to the heir, has not been seen for three days.
The comparatives plūs, minus, amplius, and longius may be seen operating without the use of quam while performing the same semantic work. Generally, these operate with a measure or number and no change in case.
Plūs septigentī captī sunt. More than seven hundred were taken.
Plūs teriī parte interfectā, nos perditī esse putāvimus, With more than one-third slain, we thought ourselves done for.
Aditus in lātitūdinem nōn amplius ducentōrum pedum relinquēbātur. An approach of not more than two hundred feet in width was left. (Genitive of measure.)
Here are some irregular adverbs that defy the rules set up in this post.
diū, diūtius, diūtissimē, for a long time, for a longer time, for the longest time
potius, ——potissimum, rather, first of all
saepe, saepius,saepissimē, often, more often/again, most often
satis, satius, —— enough, preferable
secus, sētius, —— otherwise, worse
multum (or multō), magis (or mage), maximē, much, more, most
parum, minus, minimē, not enough, less, least
nūper, ——, nūperrimē, newly, most newly
temperē, temperius, —— seasonably, more seasonably
Most of these are either disconnected from their corresponding adjectives (semantically), or are defective in either comparative or superlative form. However, the real outlier here is the multum/ō, magis/e, maximē set, which is an aggregate of various options. Multō is of course the ablative singular neuter for the positive adjective, and mage the neuter accusative of the comparative adjective.
Magis and maximē may also be paired with other adjectives to create their comparatives, especially in adjectives ending in -eus or -ius (in the positive.)
idōneus, magis idōneus, maximē idōneus, fit, more fit, most fit
The same suffixes—ārius, tōrius, and sōrius—that formed a number of adjectives in this post can also be put to use as nouns with a regular range of meanings. This meaning is often restricted to the gender of the noun formed. Again, these denote a kind of belonging.
-ārius (m.) employee in a particular field
argentārius, -ī silversmith, broker
coriārius, -ī leather worker
Corinthiārius, -ī Corinthian bronze worker (for those not in the know, Corinthian bronze had Gucci bag status in antiquity)
mirābiliārius, -ī miracle worker
operārius, ī worker, day-laborer
-ārius (f.) thing associated with a particular field
aerāria, -ae copper mine
argentāria, -ae bank
arēnāriae, -ārum sandpits (arēna, sand)
Asināria, -ae the play The Ass (with fabula, -ae implied)
-ārium (n.) thing (often a place) associated with a field
aerārium, -ī treasury
tepidārium, -ī warm bath
sūdārium, -ī towel
salārium, -ī salary
calendārium, -ī notebook (calendae, calends)
-tōria / -sōria (f.) and -tōrium / -sōrium (n.) thing (often a place) associated with a field
Agitātōria, –aeThe Driver by Platus (agitātor, driver, with fabula, -ae implied)
The adjectival suffixes -ārius, -tōrius, and -sōrius denote belonging to a group qualified by the implied content of the correspond root. Effectively, these adjectives are formed by the addition to -ius to theadjectival root -āris or the nominal root -or. Let’s build a few examples.
A few things to notice about this pattern: (i) the original base of the adjective can be just about anything—noun, adjective, verb, adverb—but the penultimate word is always a noun or an adjective. That said, (ii) the penultimate noun or adjective is not always extant in Latin; note the [brackets]. Finally, note that (iii) this set of adjectives is often theoretical—rēs bellatōriae (matters of warriors)and rēs extrāriae (matters of foreigners) probably cover half the total appearances of those two adjectives.
