Yes, Ymir Fritz (the original) could speak, but she chose not to in her Titan form, likely due to trauma and Stockholm Syndrome after her tongue was cut out and she was enslaved, a habit that carried over even after her tongue regenerated and she gained freedom in the Paths, but other intelligent Titans, like Zeke and Pieck, spoke clearly, showing the ability wasn't universal or strictly physical for Jaw Titans, but tied to the individual's psychology and relationship with servitude.
Ymir's tongue was cut out but grew back when she became a shifter, just like how Grisha's fingers and balls regenerated even though they were removed before he ate Kruger. Ymir likely simply didn't speak even after this point out of habit and psychological trauma.
Yes, her tongue was removed. When she was captured as a slave by King Fritz along with the other village people, all of them had their tongues cut off. It was shown in the anime too.
Eren offered her freedom and infinite choices, Ymir doesn't know what to do with this, so she cries.
Around 2,000 years ago, Ymir's village was attacked and enslaved by the Eldians, who also murdered her parents and cut out the tongues of the survivors.
Some Intelligent Titans could talk while others could not. Those who could not talk had mouths that physically prevented them from proper speech, such as Eren's. The ones that could talk include Ymir, Zeke, Pieck, and Lara Tybur.
Bertholdt asks Ymir if she remembers who she ate when she regained her human form. She admits she does not but apologizes when she realizes that it was probably a comrade of his.
The Simple Reason as to Why Mikasa Kissed Eren's Head. In the end, the message is clear. Mikasa kissed Eren because she loved him, and she never stopped doing so. Her affection transcended the chaos of wars and the formidable powers of Titans.
After the end of the manga, we learnt that Eren killed 80% of humanity and the 20% of it mostly lived in Paradise Island. What was believed to be a lie at the start, turned out to be a reality in the end.
When she lost Eren due to the actions of both Mikasa and Levi in the Titan Forest, Annie saw the easiest chance to return to her father was gone and she began visibly crying in her Titan form.
Ymir and Mikasa's connection explained
However, her love for King Fritz sabotaged her yearning and she awaited someone to liberate her from this torment. In theory, fans believe that Eren's Rumbling is aimed primarily at enabling Mikasa to help Ymir gain her deserved freedom.
During the two months afterward, Ymir is sent to Marley. At some point after or during the year 850, Porco Galliard is chosen to inherit the power of the Jaw Titan from Ymir.
Furthermore, she displayed signs of regret, imagining a different past where instead of saving Karl Fritz, she stayed with her three daughters. As Ymir liberated herself from the two thousand-year-long slavery, the paths ceased to exist, freeing every Eldian from the Titan's curse.
It's because of a result of the hardening serum experimentation they used. Ymir never had access to said experimentation so she never got the outlined jaw. Also she was never properly trained to use the Titan powers so she might have not known how to properly utilize it.
She is officially listed as being 17 (on the anime's official page), so she was 12 when she stopped aging and became a Titan. She is one of the older Trainees, being 14 when she enlisted. We know she did not age during her 60 years as a Titan, but resumed aging once she regained her human form.
Ymir spent about sixty years wandering outside Wall Maria as a Pure Titan. During this time, she retained little awareness or memory, which she described as having been an "endless nightmare."
Approximately 80% of all human life on the planet was ended by the time the Rumbling was stopped prematurely by the combined efforts of the remnants of Paradis Island's Survey Corps and Marley's Warrior Unit.
In season two, Eren Yeager and Armin Arlert, among other Survey Corps members, began growing suspicious of two of their comrades, Reiner Braun and Bertholdt Hoover. Reiner and Bertholdt eventually confessed the truth to Eren, admitting they were not just Marleyans undercover, but Titan shifters too.
The bloodline is still intact. The Hallucigenia (the source of all Titan powers) isn't even dead — it crawls out of Eren's head after the final fight, still alive. The foundation for the Titan system is still very much in place. The only thing that's changed is that Ymir chose to disable it.
The mangaka admitted that he wanted Eren and Mikasa to kiss each other but his shyness refrained him from doing so.
Mikasa did not get married, she was faithful till the end, the evidence is right there. She died with bandage, the flowers had symbolic meaning and she buried with Eren's scarf.
- Final battle: Mikasa, Armin, and their allies fought against Eren and his Titan form to stop the Rumbling. - Mikasa's actions: With a heavy heart, Mikasa severed Eren's head, ending the Rumbling and freeing the world from the Titans' power ¹ ³.
He and Ymir are the ancestors of every Subject of Ymir. Upon Ymir's death, Fritz forced his daughters to eat their mother's body to preserve her power.
He attacks the Scout Regiment, capturing both the unconscious Ymir and an unnamed Scout Regiment soldier. Bertholdt swallows both of them.
In response, Historia smiles and states she will always be on Ymir's side.
