1. 0:00hello Grim marians hello Rosie hi David
2. 0:02how are you good how are you good today
3. 0:04we are going to talk about run-ons and
4. 0:07comma
5. 0:08spces so a run-on sentence is what
6. 0:11happens when two independent clauses are
7. 0:14put together in one sentence without any
8. 0:16punctuation or coordinating conjunctions
9. 0:19like and but and or so Rosie what is a
10. 0:22good example of a a runon
11. 0:26sentence we bought Nails we bought a
12. 0:28hammer yeah so we can see that this
13. 0:31sentence contains two um two individual
14. 0:36independent clauses so we've got number
15. 0:38one we bought Nails Number Two we bought
16. 0:41a hammer now there are a couple of
17. 0:42different ways we could make this a
18. 0:44legal sentence but right now as it
19. 0:45stands this is a runon right so there
20. 0:48are a couple ways we could fix this
21. 0:49sentence um one way would be just to add
22. 0:52a semicolon in there sem so you've got
23. 0:55two independent clauses we bought Nails
24. 0:57semicolon we bought a hammer right
25. 1:00another way you could do that would be
26. 1:02to just add a comma and then the
27. 1:04conjunction and so you're connecting
28. 1:07those two Clauses so this is this is a
29. 1:09run-on sentence without this and and
30. 1:11this comma and it's called that because
31. 1:14it's sort of like a runaway train right
32. 1:16you know it doesn't have enough stoppage
33. 1:19in it that's how I would put it so
34. 1:21that's what a run-on sentence is and now
35. 1:23I want to talk about comma splicing and
36. 1:26the word splice not a super common term
37. 1:29if if you are neither a sailor or a film
38. 1:32editor um but splicing is a word that
39. 1:35originally meant to take two ropes
40. 1:38untangle them and weave them back
41. 1:40together it's a sailor's term related to
42. 1:42rope lines in our case for grammar uh a
43. 1:46splice a comma splice is an
44. 1:48inappropriate joining of two independent
45. 1:51clauses by using a comma so
46. 2:02so Rosie this is Lil Tony crime fighting
47. 2:05Pony right so for example in this
48. 2:07sentence I Love Lil Tony 2 Pony up to
49. 2:10the streets it's my favorite movie in
50. 2:12the Lil Tony franchise very fine series
51. 2:15of non-existent films the problem with
52. 2:17this sentence uh is that right now it's
53. 2:20got this comma in the middle of it uh
54. 2:23and this comma inappropriately joins
55. 2:26these two independent clauses oh and
56. 2:29this whole
57. 2:31time I forgot to say two independent
58. 2:35clauses inappropriately joined by a
59. 2:37comma So Okay so we've got independent
60. 2:39clause number one remember this thing
61. 2:40could stand on its own as a sentence I
62. 2:43love the name of this movie I Love Lil
63. 2:45tony2 Pony up to the streets that could
64. 2:47be its own sentence on its own end it
65. 2:48with a period period it's my favorite
66. 2:50movie in the little Tony franchise
67. 2:52period but we have these two independent
68. 2:55clauses right um we cannot join them
69. 2:58with just a comma we could say I love
70. 3:01Lil Tony 2 Pony up to the streets comma
71. 3:04and it's my favorite movie in the L Tony
72. 3:06franchise or as we did in the previous
73. 3:09uh example we could also throw in a
74. 3:11semicolon which is I think what I would
75. 3:13rather do I Love Lil Tony too Pony up to
76. 3:15the streets semicon it's my favorite
77. 3:17movie in the Lil Tony franchise and
78. 3:19Rosie you will notice that I have
79. 3:20underlined these uh these titles oh yes
80. 3:24because these are the names of published
81. 3:25works right even though we made them up
82. 3:28exactly but okay but for real I would
83. 3:30love to see like a little Tony crime
84. 3:32fighting Pony series so to review um
85. 3:37when you're looking at a runon you're
86. 3:38looking at two independent clauses that
87. 3:40are together in one sentence that are
88. 3:42joined inappropriately without
89. 3:44punctuation or conjunctions uh so we
90. 3:47bought Nails we bought a hammer there's
91. 3:49there's not really a place to know where
92. 3:52the division between Clauses is in that
93. 3:57uh and so the thing to do is to either
94. 3:58is to add some kind of is to add a comma
95. 4:01uh and some and a
96. 4:03conjunction or to combine them using a
97. 4:06semicolon uh the same deal with a commas
98. 4:08splice it's just that a comma splice is
99. 4:11a runon that hasn't been fixed all the
100. 4:13way right the Comm is being used but we
101. 4:16need some bigger
102. 4:18punctuation in place of the comma
103. 4:20something like a
104. 4:21semicolon uh in order to make a
105. 4:24distinction between those two
106. 4:26independent clauses so that is how you
107. 4:28identify and fix run-ons and comma
108. 4:30splices you can learn anything David out
