Could Ukraine hold a presidential election right now? Will Europe use frozen Russian assets to fund war? How can Ukraine rebuild China ties? 'Ukraine is running out of men, money and time' At least four people were killed in a Russian drone attack on a passenger train in Ukraine's Kharkiv region, Ukrainian President Volodymyr Zelenskyy said on Telegram. Zelenskyy added that four people were still missing, and that two people were injured in the attack.

A Russian drone attack on a 25-storey residential building in Ukraine's capital, Kyiv, injured eight people, including a four-year-old girl, the head of the city's military administration, Tymur Tkachenko, said. The overnight attack was part of a barrage of "324 drones, four cruise missiles and three ballistic missiles", across the country, the Ukrainian Air Force said. The attack was focused on Starokostiantyniv, home to a major air base, the Air Force added. Ukraine's Air Force said it downed 309 drones and two missiles, while 15 drones and two missiles hit targets in three locations, without specifying where. The attack started a fire in Kropyvnytskyi, in central Ukraine, local officials said, but no injuries were reported.

Russian bombardments in eastern Ukraine ramped up overnight, killing two people, as Ukraine hit Russia's Engels military airfield in the country's southwest region of Saratov with drones. Both Russia and Ukraine stepped up aerial attacks in the early hours of Thursday as United States President Donald Trump pushes both sides to agree to a ceasefire after more than three years of fighting. Ukrainian officials in the northeastern Sumy and Kharkiv regions said two people were killed and several others injured after Russia dropped more than three dozen glide bombs on the towns in the border regions. Russian drone attacks on the town of Kropyvnytskyi, hundreds of kilometres from the front line, wounded 14 people and damaged rail infrastructure. "Kropyvnytskyi underwent the most massive enemy attack. Peaceful residential buildings were destroyed," regional governor Andriy Raikovych said.

A Ukrainian drone attack targeting an armoury has caused a giant fireball, leading to a partial evacuation in western Russia. The attack, reported early on Wednesday, targeted a large arsenal close to the town of Toropets, some 400km (250 miles) northwest of Moscow in the Tver region. It illustrates Ukraine's continued effort to show it can strike at targets deep inside Russia. The drone attack caused an "extremely powerful detonation" and destroyed a large warehouse of the Main Missile and Artillery Directorate of the Russian Ministry of Defence and sparked a fire 6km (3.7 miles) wide, an unnamed source from the Ukrainian security services said. "The warehouse contained missiles intended for Iskander tactical missile systems, Tochka-U tactical missile systems, guided aerial bombs and artillery ammunition," the source told news wires.

Language is in a continuous process of change that occurs permanently, language change being the phenomenon that drives language evolution, as a process of adaptation to the environment and the ways other speakers use the language [3, 2]. The various instances of language change are classified into different categories, such as regular phonetic changes, changes in word usage, and changes in the way words appear together, i.e., syntactic changes. Although it is usually a continuous process that follows regular patterns, very abrupt changes in the meanings of words can still occur, usually motivated by a change in the context a community lives in [15, 9, 7]. Semantic change, as a phenomenon permanently present in language evolution, is an important aspect that should be taken into account when working with historical data[1]. Historical linguists, lexical typologists, and other humanities and social science experts have studied the meaning of words and how it changes over time.
