La pinglo tenas la rubandon sur la teksaĵo.

Because rubandon is the direct object of the verb tenas.

In Esperanto, the thing directly affected by the action usually takes -n:

• La pinglo tenas la rubandon. = The pin/needle holds the ribbon.

Here:

• la pinglo = the subject, the thing doing the action
• tenas = holds
• la rubandon = the object, the thing being held

That is why rubando becomes rubandon.

Because sur here shows a location, not movement toward a place.

• sur la teksaĵo = on the fabric/textile
• sur la teksaĵon would suggest movement onto the fabric

So:

• La pinglo tenas la rubandon sur la teksaĵo. means the ribbon is already positioned there, and the pin is holding it there.

A helpful comparison:

• Ĝi estas sur la tablo. = It is on the table.
• Mi metas ĝin sur la tablon. = I put it onto the table.

La is the Esperanto definite article, meaning the.

So:

• la pinglo = the pin / the needle
• la rubandon = the ribbon
• la teksaĵo = the textile / the fabric / the woven material

Unlike English, Esperanto has only one article form:

• no a/an
• just la for the

It does not change for gender, case, or number, though the noun itself can change:

• la rubando = the ribbon
• la rubandoj = the ribbons
• la rubandon = the ribbon (object)
• la rubandojn = the ribbons (objects)

Tenas comes from the verb teni, meaning to hold, to keep, or to support.

The ending -as marks the present tense in Esperanto.

So:

• teni = to hold
• tenas = holds / is holding
• tenis = held
• tenos = will hold
• tenus = would hold
• tenu = hold! / let ... hold
• teni = to hold

In this sentence, tenas simply means holds.

Pinglo can cover several similar sharp objects, depending on context, such as a pin or sometimes a needle-like fastener.

In this sentence, since it is holding a ribbon onto fabric, pin is probably the most natural English choice. But the exact translation can depend on the situation.

Esperanto words are often a bit broader than one exact English word, so context helps determine the best translation.

Teksaĵo comes from:

• teksi = to weave
• -aĵ- = a concrete thing made from an action or quality
• -o = noun ending

So teksaĵo literally means something like a woven thing or woven material.

Depending on context, it could be translated as:

• fabric
• textile
• woven cloth
• material

This is a useful example of Esperanto word-building.

Compare:

• teksi = to weave
• teksaĵo = a woven item/material
• teksisto = a weaver
• teksilo = a loom or weaving tool, depending on context

Yes, Esperanto word order is fairly flexible, because the -n ending helps show what the object is.

The normal order here is:

• La pinglo tenas la rubandon sur la teksaĵo.

But other orders are possible, especially for emphasis:

• La rubandon tenas la pinglo sur la teksaĵo.
• Sur la teksaĵo la pinglo tenas la rubandon.

Even if the order changes, la rubandon is still the object because of the -n.

That said, the most neutral and natural order is usually subject + verb + object.

It is most naturally understood as telling you where the holding situation happens: the ribbon is being held on the fabric.

In practice, it relates to the whole scene:

• the pin is holding
• the ribbon is what is held
• sur la teksaĵo tells you the location

English works similarly:

• The pin holds the ribbon on the fabric.

So it does not have to belong only to one single word; it describes the placement involved in the action.

A rough pronunciation is:

tek-SAH-zho

More exactly:

• tek = like tech without the final ch
• sa = sah
• ĵ = like the s in measure or the g in genre
• o = a short pure o sound

So:

• teksaĵo ≈ tek-SAH-zho

Also, the stress in Esperanto is always on the second-to-last syllable, so the stress is on sa:

• tek-SA-ĵo

Grammatically, yes:

• Pinglo tenas rubandon sur teksaĵo.

But that sounds much more general or less specific, something like:

• A pin holds ribbon on fabric or
• Pins hold ribbon on fabric, depending on context

The version with la sounds like it refers to specific things already known in the situation:

• the pin
• the ribbon
• the fabric

So la makes the sentence more definite and concrete.
