Post casum femur quoque ei dolet, sed ambulare lente adhuc potest.

Because post is a preposition that takes the accusative when it means after.

• post casum = after the fall / after the accident

So casum is the accusative singular of casus.

Here casus most naturally means a fall or an accident.

Although casus can have several meanings in Latin, in this context post casum clearly means something like after the fall or after the accident/injury.

In Latin, doleo often works differently from English hurt.

Latin commonly says:

• the body part hurts to someone

So:

• femur dolet = the thigh hurts
• ei femur dolet = his/her thigh hurts or more literally the thigh hurts to him/her

That is why femur is in the nominative: it is the grammatical subject of dolet.

Femur means thigh.

In this sentence it is nominative singular, because it is the subject of dolet.

It is also worth noticing that femur is a neuter noun, so the nominative singular form is simply femur.

Ei is the dative singular form of is, ea, id, and here it means to him or to her.

With verbs like dolet, the person who feels the pain is often put in the dative:

• ei dolet = it hurts him/her
• femur ei dolet = his/her thigh hurts

So ei is not the subject. It marks the person affected.

Quoque means also or too, and it usually comes after the word it emphasizes.

So:

• femur quoque = the thigh too / the thigh also

This suggests that something else was already hurting, and now the sentence adds that the thigh also hurts.

Because potest is followed by an infinitive.

• potest = he/she can
• ambulare = to walk

Together:

• ambulare potest = he/she can walk

This is a very common Latin construction:

• possum + infinitive = can / am able to ...

Lente means slowly.

It is an adverb, modifying ambulare:

• ambulare lente = to walk slowly

So it tells us how the person can walk.

Here adhuc means still.

So:

• adhuc potest = he/she still can

The idea is that even after the fall, and even though the thigh hurts, the person still has the ability to walk.

Because its subject, femur, is singular.

• femur = the thigh
• dolet = hurts (singular)

If the subject were plural, the verb would also be plural.

The core structure is:

• sed ... potest = but ... can
• ambulare = the infinitive depending on potest
• lente = modifies ambulare
• adhuc = modifies the idea of still can

So:

• sed ambulare lente adhuc potest = but he/she can still walk slowly

A more literal breakdown would be:

• but to walk slowly still he/she is able

The word order is normal for Latin, which is much freer than English.

Latin often arranges words for emphasis rather than sticking to one fixed pattern. A few things stand out:

• post casum comes first to set the time/context: after the fall
• femur quoque places emphasis on the thigh too
• ei comes near dolet, which fits the dative construction
• adhuc appears near potest to stress still can

So the sentence is not strange; it is just using Latin’s flexible word order naturally.

Yes.

By itself, ei can mean:

• to him
• to her
• sometimes to it, depending on context

Latin often leaves gender to be understood from the wider context, so the sentence alone does not force him or her.

It has two main clauses joined by sed:

1. Post casum femur quoque ei dolet

   • After the fall, his/her thigh also hurts

2. sed ambulare lente adhuc potest

   • but he/she can still walk slowly

So the overall pattern is:

• problem: the thigh hurts
• contrast: but walking is still possible

That contrast is exactly what sed is signaling.
